World“s largest scale alkaline water electrolysis system with power of 10 Megawatt from Asahi Kasei selected for Fukushima Hydrogen Research Center

Düsseldorf, August 14, 2018 – Asahi Kasei and its subsidiary Asahi Kasei Engineering Corp. have received an order from Toshiba Energy Systems & Solutions Corp. for an alkaline water electrolysis system of the world-leading scale of 10 MW in a single unit to be installed at the Fukushima Hydrogen Research Field in Namie, Futaba, Fukushima, Japan.

The development of a large-scale alkaline water electrolysis system featuring high energy efficiency and outstanding responsiveness with fluctuating output was achieved based on Asahi Kasei“s world-leading chlor-alkali electrolysis technology. The project is being supported by Japan“s New Energy and Industrial Technology Development Organization (NEDO).

Toshiba Energy Systems & Solutions was commissioned by NEDO to implement a „Hydrogen from Renewable Energy Project“ in Namie, as a technological development project.

Integrated with a large-scale solar power generation plant, the electrolysis system will form a core part of the Fukushima Hydrogen Research Field scheduled for test operation in the autumn of 2019 and start-up in the summer of 2020.

Asahi Kasei“s alkaline water electrolysis system is an example of „power-to-gas“ technology to convert renewable energy into clean hydrogen which is expected to be widely utilized in transportation and industrial applications as a substitute for fossil fuel. The market is expected to grow significantly with the shift to a low-carbon society.

Participation in this project accords with Asahi Kasei“s medium-term strategic objective of providing solutions to society in the area of clean environmental energy.

Science Research Technology

Gentle finishing of extremely hard surfaces

Overlapping rotational work piece movement is the basis for even, all-around surface finishes

Gentle finishing of extremely hard surfaces

The spindles allow the processing of batches of up to 18 work pieces. For this photo different work

At this year“s IMTS Walther Trowal is introducing the new drag finisher M-TMD 6M for treating high-value components that require a first-class surface quality. The new drag machines will place a mirror polish on the hardest materials – even on ceramic components. With these machines the costs for polishing can be reduced to a fraction of the costs for manual surface grinding and polishing. But even more important: They ensure absolutely repeatable, high-quality finishing results within an extremely narrow tolerance band.

Walther Trowal developed these new machines specifically for treating high-value components requiring extremely careful handling for the complete finishing process. For example, they are utilized for finishing the surface of turbine blades, impellers for turbo chargers, precision components for pumps and compressors as well as for orthopedic implants.

The new drag machines of the M-series have a carousel with multiple rotating workstations. In turn each workstation is equipped with spindle heads containing several spindle drives onto which the work pieces are attached with special fixtures. In addition, these machines also contain a stationary work bowl filled with grinding or polishing media. As the work pieces are „dragged“ through the stationary media mass, the simultaneous rotational work piece movement by carousel, workstations and spindles creates different overlapping patterns, which ensure an even and intensive coverage of the complete work piece surface.

Christoph Cruse, director of sales at Walther Trowal, foresees a big demand for these machines at some of his customers who produce delicate, high-value components. He explains: „With our new machines we want to assist the manufacturers of work pieces that must receive the best possible surface finish, and where even the slightest surface flaw or scratch might cause them to be scrapped. Furthermore, we target parts where deviations from the dimensional specifications of a few thousands mm can be a detrimental. The M-TMD drag finishers with their perfect surface coverage open brand-new possibilities for finishing such work pieces.“

Die M-TMD 4 drag finisher is equipped with four work stations and can process 12 parts in one single batch; the M-TMD 6 – with six work stations allows batch sizes of up to 18 pieces.

At this year“s IMTS Walther Trowal also displays a range of mass finishing equipment including rotary vibrators, the MV multi vib vibrators and a high-energy centrifugal disk finishing machine.

One drag finishing success story:
Polishing of the extremely wear resistant ceramic coating on orthopedic implants

One example for the successful use of the new drag finishers is a process, specifically developed by Walther Trowal, for polishing of knee femorals made from a chromium-nickel alloy, which are covered with a ceramic coating applied with a special vapor deposit method. To date these parts had to be finished manually in time consuming multiple steps with the risk of high quality fluctuations.

After a pre-grinding step the ceramic coating is polished in the new M-TMD drag finisher with a polishing medium specifically developed for this application. The result: Although the ceramic coating is extremely hard, the drag finisher produces a very smooth, shiny and highly wear resistant finish from the initially rough surface condition. The new coating extends the fatigue life of the implants from to date about 20 up to 30 years!

In developing this process Walther Trowal took an entirely new approach. Instead of using relatively soft polishing materials the company is adding an extremely hard substance to the polishing medium, namely diamond powder.

Christoph Cruse explains the advantages of the new process as follows: „Soft materials can be polished relatively easily. But the manual polishing of extremely hard coatings has been extremely difficult, especially because an even surface finish is essential for the functionality of the component. In the case of vapor deposit coating, with a layer thickness of just a few microns, it is essential not to remove too much of the coating material from the part surface. With the M-TMD drag finishing technology and the new polishing media we have resolved this difficulty: The finish is absolutely even on the entire surface area of the implants.“

The technical details

In standard drag finishers the work pieces are directly mounted to the workstations and „dragged“ through the stationary media bed producing an extremely high processing intensity. This method is more than adequate for most work pieces and produces excellent finishing results.

The new M-TMD systems allow one additional rotational movement, namely that of the spindles mounted to the workstations. The multi-spindle heads on the workstations can be also be angled allowing the adaptation of the media coverage on the work piece surface to different work piece geometries.

All process steps, from cut-down, over surface smoothing to the final polishing, take place in the same machine, without having to remove the work pieces from the spindles.

The new drag finishers are suitable for dry as well as wet processing. In wet processes for cut-down, surface smoothing and, occasionally, for polishing, special finishing compounds are used. For the targeted edge radiusing within a tolerance range of a few thousands mm, like for example for tungsten carbide drill bits or milling tools, dry grinding media are utilized. Dry processing is also used for high gloss polishing with special pastes and polishing media.

(Stuttgart/Reutlingen) – During the Science2Start award ceremony held at the BioRegio STERN 2018 summer party, four teams of scientists and entrepreneurs were honoured for their ideas, all of which boast enormous economic potential. First place was awarded to Professor Bernhard Hirt from the University Hospital Tübingen’s Institute of Clinical Anatomy and Cell Analysis for his idea of the formaldehyde substitute „aminolipin“. Second place went to a software solution for genetically analysing bacterial strains to effectively combat multiresistant bacteria. Tying in third place were two lab-on-a-chip test systems for developing medication to treat neurodegenerative and retinal diseases. The Reutlingen-based artist Jenny Winter-Stojanovic wowed a long list of guests from the worlds of science, business and politics with a spectacular live installation created with cling film in the Tübingen observatory.

Last Thursday, the 2018 winners of the tenth „Science2Start“ ideas competition were announced at this year’s joint summer reception held at the Tübingen observatory. The event was organised by BioRegio STERN Management GmbH, the Verein zur Förderung der Biotechnologie und Medizintechnik e. V. (Society for the Promotion of Biotechnology and Medical Technology) and Tübingen-Reutlingen Technology Park (TTR). In his keynote speech on leadership, Dr. Peter Heinrich – serial entrepreneur, founder of Medigene AG, and co-founder and spokesman for the Executive Board of BIO Deutschland – quoted the poet and author Antoine de Saint-Exupery: „If you want to build a ship, don’t drum up the men to gather wood, divide the work and give orders. Instead, teach them to yearn for the vast and endless sea.“ Giving some advice to the future entrepreneurs, Dr. Heinrich then said: „The trick to leadership lies, among other things, in creating an atmosphere and the necessary conditions to motivate people to work together towards goals.“

Although the four winners of the tenth ideas competition are just starting out in the world of business, the specialist panel of Science2Start judges viewed their projects as boasting great economic potential. Leading the way was Professor Bernhard Hirt from the University Hospital Tübingen’s Institute of Clinical Anatomy and Cell Analysis with his idea of the formaldehyde substitute „aminolipin“. Second place was awarded to Dr. Wei Ding and Benjamin Buchfink from the Max Planck Institute for Developmental Biology in Tübingen for their „PanX+“ software, which is designed to genetically analyse bacterial strains and thus effectively combat multiresistant bacteria. The Natural and Medical Sciences Institute (NMI) at Tübingen University and the Fraunhofer Institute for Interfacial Engineering and Biotechnology (IGB) from Stuttgart tied in third place with their lab-on-a-chip test systems for developing medication. The „3D in vitro platform“ developed by Dr. Paolo Cesare targets neurodegenerative diseases, while the „retina-on-a-chip“ presented by Dr. Christopher Probst focuses on treating retinal diseases. The prize money awarded totalled 4,500 euros and, as in previous years, was donated by Voelker & Partner, a firm of lawyers, tax consultants and auditors.

At the subsequent summer reception organised by BioRegio STERN Management GmbH, numerous researchers, entrepreneurs and politicians discussed various exciting topics until late into the evening. One topic of conversation was Jenny Winter-Stojanovic – the Reutlingen-based artist gave guests a live performance, producing a sculpture with cling film that, in combination with the lighting, created a sensational membrane structure stretching from around the iron pavilion into the Tübingen observatory. Hosting the event, BioRegio STERN’s Managing Director Dr. Klaus Eichenberg was delighted to see the art installation give guests food for thought. „Entrepreneurs need to have inspiring ideas and implement them creatively if they want scientific ideas to result in success. They need good connections, too. We are able to help in this respect – by hosting this event, for example,“ said Dr. Eichenberg.

Descriptions of winning projects from the 2018 Science2Start ideas competition

1st place: „Aminolipin“ developed by Prof. Bernhard Hirt from the Institute of Clinical Anatomy and Cell Analysis at Tübingen University
The team of the Institute of Clinical Anatomy and Cell Analysis has developed the substance Aminolipin as a fixing and preservation agent for solid specimens, organs and tissue. It inhibits enzymes that are responsible for decomposition, exhibits a wide antimicrobial efficacy spectrum and is highly efficient in halting the process of putrefaction. Until now, medical professionals have used the toxic and carcinogenic substance formaldehyde to preserve biological tissue, and even entire human bodies. Corpses prepared with Aminolipin closely resemble live patients in form, colour and look and therefore help to enhance doctors‘ training.

2nd place: „PanX+“ developed by Dr. Wei Ding and Benjamin Buchfink, Max Planck Institute for Developmental Biology, Tübingen
PanX+ is an interactive software solution for analysing and visualising bacteria genomes to fight off multiresistant bacteria. Dr. Ding developed panX software to quickly evaluate and interactively visualize the pangenome – in other words, the entire gene set of bacteria strains. His team, known as PathoVis, has developed the new PanX+ software, which makes it possible to analyse enormous volumes of data in less than a day. The epidemiological data is visualised, which allows researchers to investigate the causes of bacteria and give hospitals and public health authorities recommendations on how to prevent multiresistant bacteria from spreading further.

3rd place: „3D in vitro platform“ developed by Dr. Paolo Cesare, Natural and Medical Sciences Institute (NMI) at Tübingen University
Dr. Paolo Cesare’s team has produced an innovative brain-on-a-chip platform and managed to substantially develop Cesare’s MEAFLUIT system of microelectrode arrays fitted with microfluid technology, which secured them a Science2Start award back in 2015. The test system can be used to cultivate and interconnect human neurons. In this way, the 3D in vitro platform makes it easier to develop effective medication for Alzheimer’s and Parkinson’s disease, for example, and circumvents the need for animal testing.

3rd place: „Retina-on-a-chip“ developed by Dr. Christopher Probst, Fraunhofer IGB, Stuttgart
„Retina-on-a-chip“ is an innovative 3D in vitro test system. Researchers from the Fraunhofer Institute for Interfacial Engineering and Biotechnology (IGB) and Eberhard Karls University of Tübingen have succeeded in simulating the human retina in vitro to enable scientists to undertake more efficient pharmacological drug research for treating as yet incurable retinal diseases such as age-related macular degeneration and retinitis pigmentosa. Compared to current testing methods, the 3D retina model and the vasculature-like perfusion of nutrients gives researchers a much better insight into their object of study. The use of pluripotent stem cells as the raw material also helps to reduce the number of tests carried out on animals in pre-clinical drug research and testing.

Optic chip with a long service life

Success for Retina Implant – retinal implant still functioning after more than 50 months

Optic chip with a long service life

(Reutlingen) – The subretinal implant from Retina Implant AG has successfully demonstrated its long service life under real-life conditions. Implanted back in 2014, the chip is still functional and has enabled a previously completely blind RP patient, now in her 70s, to perceive light. The fact that the implant has thus exceeded a service life of over 50 months is a great technological success for the Reutlingen-based medtech company.

Retinitis pigmentosa (RP) is a degenerative retinal disease that leads to the destruction of the retina and often total blindness in the final stage. It is regarded as a „rare disease“, yet affects 20,000 to 30,000 people in Germany alone and around three million individuals worldwide. Retina Implant AG from Reutlingen has developed a subretinal implant that is able to restore partial sight to people who perceive very little or no light due to various forms of degenerative retinal diseases such as RP.

In Tübingen, an RP patient who had already lost all her sight received the implant in 2014. The chip implanted in the patient, now in her 70s, has been in operation for more than four years – and still functions as it did in the beginning. For instance, the patient can identify light sources and therefore find her way around more easily. „One of the greatest challenges when developing the implant was ensuring the camera chip in the eye would remain functional over many years,“ explains Dr. Alfred Stett, CTO of Retina Implant AG. „Unlike pacemakers and neurostimulators, which have their electronics and battery packaged in a fixed, hermetically sealed casing, our electronic chip is in direct contact with the retina – a light-permeable barrier layer that is a few micrometres thick is the only form of protection.“

The subretinal implant features 1,600 photodiodes and stimulation contacts that partially replace photoreceptors destroyed by RP. The chip is only around 12 square millimetres in size and is placed directly below the fovea centralis, which means it can move with the eye to locate objects. The latest generation of the implant, known as the RETINA IMPLANT Alpha AMS, was awarded CE certification back in 2016. In Germany, the cost of the implant is reimbursed by the statutory health insurance providers.

„Our forecasts regarding shelf life were previously based on ageing tests conducted in the laboratory and on model-based estimates of service life that are commonplace in the aviation industry, for example. These tests and estimates predicted a service life of 4.7 years. Our patient’s experience shows that we are on the right path. This success is the result of 15 years of intensive research and development to give blind people fresh hope,“ says Dr. Stett.

Dates
25 August 2018 Patient information day for congenital retinal diseases at Knappschaftsklinikum Saar GmbH, An der Klinik 10, 66280, Sulzbach, Germany, Augenklinik Sulzbach (Sulzbach Eye Hospital).

About Retina Implant AG
Retina Implant AG researches and develops innovative treatments and high-tech products for people suffering from retinitis pigmentosa (RP). The subretinal RETINA IMPLANT Alpha AMS can help blind patients regain a certain degree of useful sight. The CE-approved microchip is implanted beneath the retina (subretinally) at specialist RI implantation centres.
Transcorneal electrical stimulation (TES treatment) with the RI OkuStim® system offers RP patients with sufficient residual vision the opportunity to slow down the progression of the disease.
The company, based in Reutlingen, employs around 45 people and is managed by Reinhard Rubow (CEO and speaker of the Management Board), Jürgen Klein (Member of the Board, Sales & Marketing) and Dr. Alfred Stett (CTO, Member of the Board).

Ideas brought to life in Anatomy

Incisions and insights workshop series – „Heart, lungs, thorax“

Ideas brought to life in Anatomy

Workshop „Incisions and insights“ at the Institute of Clinical Anatomy and Cell Analysis (Source: M. Latz/BioRegio STERN Management GmbH)

(Stuttgart/Tübingen) – The „Incisions and insights – medtech engineers and medical practitioners in dialogue“ workshop series continued in June 2018, focusing on the heart, lungs and thorax. BioRegio STERN Management GmbH is organising this exceptional series of events in collaboration with the Inter-University Center for Medical Technologies Stuttgart-Tübingen (IZST) and the Verein zur Förderung der Biotechnologie und Medizintechnik e. V. (Society for the Promotion of Biotechnology and Medical Technology). This fourth event once again saw medical directors and senior consultants meet with medtech engineers directly at operating tables in Anatomy to discuss the innovations they desire and need.

The specialists from University Hospital Tübingen have already dubbed the series of events „Make a wish“, as it gives them the opportunity to express their wishes to medtech engineers for new or improved instruments and equipment unfiltered by purchasing or marketing departments. The fourth workshop in the series focused on the heart, lungs and thorax. Alongside the live streaming of surgery and practical exercises in the operating theatre at the Institute of Clinical Anatomy and Cell Analysis, the medical directors and senior consultants from University Hospital Tübingen Dr. Helene Häberle, Senior Consultant Surgeon at the Intensive Care Unit, Prof. Alfred Königsrainer, Medical Director of General, Visceral and Transplant Surgery, Prof. Christian Schlensak, Medical Director of Thoracic and Cardiovascular Surgery, and Prof. Roland Syha, Head of Interventional Radiology, discussed potential innovations. During this session, Prof. Peter P. Pott, Head of the Institute of Medical Device Technology at the University of Stuttgart, explained what is technically feasible. Prof. Arnulf Stenzl, Medical Director of the University Department of Urology and Head of the Inter-University Center for Medical Technologies Stuttgart-Tübingen (IZST), co-chaired the workshop together with the host Prof. Bernhard Hirt, Director of the Institute of Clinical Anatomy and Cell Analysis. Around 40 medtech company representatives attended the event, which offered them an impressive range of incisions and insights.

A surgeon got straight to work on artificial heart implantation and minimally invasive lung and oesophagus surgery on an anatomical specimen. While feeding a tube into the trachea, he explained to the medtech engineers – and to medical students linked via live stream – why a second working channel would be useful: „A further piece of equipment, such as forceps, often needs to be inserted. This may also result in bleeding, which blocks the one channel.“ During the subsequent demonstration of a minimally invasive lobectomy – the removal of an organ lobe – the operating team explained the need for a second camera in order to monitor inside the thorax from an additional angle. A stapler that can attach staples and bend 90 degrees was also added to the wish list, as was a cleaning function for the camera lens. However, the surgeons‘ discussion with Prof. Pott quickly revealed that much of what is technically feasible is not at all practicable in everyday surgery. „Extra functions require cables and switches. Yet at the same time, the equipment is expected to become increasingly smaller and easier to handle.“ Physical limitations also curb miniaturisation: „A camera lens can only be reduced in size to a certain extent, otherwise it no longer transmits anything,“ explained Prof. Pott.

The subsequent artificial heart transplant once again showed that the surgeons attach great importance to small and agile instruments to open up the chest as little as possible, as this is often associated with major discomfort for patients. To implant the 200-gramme artificial heart, just two incisions are needed. Unfortunately, one of these remains permanently open, as the control and battery power cables need to be fed outside. „Of course there’s already the option of a cable-free power supply for hearing aids, for example,“ said Prof. Pott. „If this fails, the patient no longer hears anything. But if this fails in the case of the heart, the patient expires.“

The demand for innovation is therefore high, giving developers and users plenty to discuss, and this is unlikely to be exhausted at the next event in February 2019, which will focus on „Extremities and the musculoskeletal system“. „As far as we know, there’s no comparable event anywhere else in the world,“ explained Dr. Klaus Eichenberg, co-organiser and Managing Director of BioRegio STERN Management GmbH. „Surgeons are calling for new processes and instruments. I’m confident the local medtech businesses will take up this challenge and bring to life some of the ideas that were first formulated here.“

Düsseldorf, July 5, 2018 – On May 26, Asahi Kasei Medical, a leading manufacturer of products for hemodialysis and therapeutic apheresis treatment launched the first Apheresis Meeting Industry Symposium within the Industry Symposium program of the 55th ERA-EDTA Congress in Copenhagen. 500 participants joined the Symposium.

Therapeutic apheresis is used to treat a wide range of intractable diseases, such as autoimmune diseases including rheumatoid arthritis, peripheral arterial disease, ulcerative colitis, neurological diseases or lipid disorders. Asahi Kasei Medical, founded in 1974 and the first company to globally introduce the hollow fiber separation technology, is offering therapeutic apheresis products that use membrane separation and selective adsorption technology to enable the treatment of many intractable diseases that cannot be treated using drugs. Therapeutic apheresis is increasingly used in the field of preventive medicine.

The membrane used in hollow fiber separation technology only permits plasma and proteins to pass through. Cellular components such as erythrocytes, leukocytes and thrombocytes are filtered out through the fine pores of the special hollow fibre membrane. Plasma and pathogenic substances can be removed, the plasma can be purified and returned to the patient.

During the Apheresis Meeting Industry Symposium, Professor Antonio Santoro (Bologna, Italy) chaired three sessions on Therapeutic Apheresis respectively held by Professor Lionel Rostaing (Grenoble, France), Dr. Alfonso Ramunni (Bari, Italy) and Professor Christoph Wanner (Würzburg University, Germany).

The first session by Professor Christoph Wanner titled „Lipid Apheresis and PCSK9-Antibodies:
Complementary or Competitive?“ explained how high plasma Lipoprotein(a) levels are related with the risk of myocardial infarction in the general population and which preventive action the apheresis treatment exerts by removing Lipoprotein(a) from patient“s blood.

The second session, „Rheopheresis in peripheral artery disease“ presented by Dr. Alfonso Ramunni, focused on removal of Fibrinogen from patient“s plasma and how it impacts peripheral vascular diseases such as Ischemic Diabetic Foot, Critical Limb Ischemia, Sudden Hearing Loss or Age-Related Macular Degeneration.

The third and last session, held by Professor Lionel Rostaing, „Desensitization in ABO incompatible kidney transplant candidates in order to achieve long term outcome“ explained about apheresis treatment efficiency with graft survival in ABO incompatible patients.

ERA-EDTA (European Renal Association – European Dialysis and Transplant Association), founded in 1963 aims at fostering the advancement of science and clinical work in nephrology, dialysis, renal transplantation, hypertension and related diseases with a strong focus on bettering patient“s health. It counts 7, 253 members.

ERA-EDTA Congress is the International annual scientific event that gathers about seven thousand physicians from Europe and worldwide. This year“s Congress took place in Copenhagen on 24-27 May 2018.

DKT 2018: ZEON Strengthens Market Leader Position in Specialty Rubbers

DKT 2018: ZEON Strengthens Market Leader Position in Specialty Rubbers

Zeon Corporation Plant

ZEON Corporation, Japan, represented by the European subsidiary ZEON Europe GmbH exhibits at the Deutsche Kautschuk Tagung (DKT; German Rubber Conference) in Nuremberg, 2-5 July 2018, a triannual international major event for the rubber industry. In hall 12 booth 325, ZEON will meet and greet the business partners and present the latest innovations and updates of ZEON activities, particularly in Europe. Interested parties are invited to discuss how to improve the long term performance of HNBR compounds at ZEON“s presentation in the conference program (lecture session 3 July, 8:30 a.m., Hall Paris). ZEON brings the following highlights into the focus of this event:

HNBR – Hydrogenated nitrile rubbers are well known in the automotive industry for their resistance to fuels, lubricating oils, coolants and other media and have a long history in the engine sealing components. However, the recent trends in engine cooling have resulted in the use of more aggressive coolant technologies and higher temperature performance requirements, from 125°C in the past up to 150°C recently and in some cases in combination with low temperature requirements as low as -40°C. To tackle this challenge has become the focus, in order to bring Zetpol® to the higher competitive level like Fluoroelastomers.

Based on the next generation polymer technology, ZEON introduced high performance HNBR (HP-Zetpol®), that contain unique architecture and a specific cure site monomer. ZEON“s application technologists have developed compounds based on this novel material, which can offer better heat resistance and significantly improved compression set resistance compared to the conventional peroxide-cured HNBR. Dr. Björn Nelson, Technical Service Manager concludes, „the improvement of compression set resistance is magnified over longer ageing time and especially in this cross-sectioned articles, such as O-rings. This makes HP-Zetpol® a material of choice for the recent coolant technologies“. Detailed information will be presented in the lecture program.
ZEON enhances the capability to supply the innovative material HP-Zetpol®, hence the production capacity in Kawasaki, Japan will be extended in the near future. In parallel ZEON is continuously increasing the efficiency of two other Zetpol® production facilities in Takaoka, Japan and in Texas, USA in order to fulfil steadily increasing market demand of ZEON“s top quality products.

HT-ACM – The automotive region Europe is the key market for ZEON“s innovations in the acrylic rubbers. HyTemp® ACM have been established in the automotive market for sealings and gaskets as well as for hoses in the engine air management system. Its resistance against high temperature and oil supports the development of most popular modular engine design at OEMs. ZEON keeps developing new types of acrylic rubbers to face the constantly challenging market requirements: engine downsizing, combined platforms and emission reductions. The novel HyTemp® H570 is able to maintain the maximum high temperature resistance of HT-ACM whilst at the same time improving low temperature and oil resistance performances. For CAC hose applications, ZEON continues to improve the polymer robustness to increase the physical properties retention after ageing, which is crucial for certain OEM specifications, without jeopardizing the dynamic resilience and extrusion speed. Talk to us for further information!

TPV – Zeotherm®, a familiar brand name for heat and oil resistance applications of thermoplastic vulcanizate in the automotive sector. The unique properties of Zeotherm®, a polyblend of polyamide and acrylic rubber, offer various advantages like weight and cost reduction, simple design, easy processing and recyclability. The blow moulding grades of Zeotherm® with a hardness range of 90 Shore A up to 40 Shore D have settled their position in the market of cold side CAC hose applications.

NBR – Beside the standard and pre-crosslinked nitrile rubber portfolio, ZEON is also well known as a specialty nitrile rubber producer. The specialty nitrile rubbers vary their forms from standard bale rubber, to liquid (Nipol® 1312) or powder (Nipol® 1411) grades, originated from the production facility in Louisville, Kentucky, USA. Nipol® 1312 has proven its unique function to enable the production of soft elastomer articles without using high level of oil or plasticizer. It eases the processing and prevents oil bleeding, since the liquid NBR is curable into the polymer matrix. Powder NBR is perfectly utilized in a special dry compounding process in the area where the end products need to have high stiffness but also a certain extend of flexibility, e. g. in the brake pad application. Both liquid and powder nitrile rubbers are ideal material for adhesive application, also where a solvent free system is desired.

SSBR, Li-BR, Hydrocarbon Resin – The tyre industry is one of ZEON“s main market segments. The newly founded joint venture of ZEON Corporation and SUMITOMO Chemicals (ZS Elastomers) in Japan consolidates their tyre rubbers product portfolio, solution-SBR and Li-catalysed-BR, supplying the global tyre industry with world class products. The functionalization technologies coming from both mother companies lead to a special synergy effect and become the solution in the developments of future green tires. „Our products, particularly the functionalized S-SBR and Li-BR, support the global tyre industry to continuously optimizing the balance between low rolling resistance, wet grip, wear resistance and good processability“, says Hiroyuki Adachi, Tyre Rubber Commercial Manager, „they are the key features of modern high performance eco tyre“.

ZEON hydrocarbon resins (Quintone®), furthermore, has become an essential part as performance resins in the modern tyre technology. In addition to the standard functions of hydrocarbon resins as tackifier and softener, which are necessary for compound processability, Quintone® improves other tyre performance metrics, such as the tip resistance, chip-chunk resistance, and anti-crack behaviour. Both in specialty rubbers and resins, ZEON“s R&D activities result on innovative materials that support tyre compounders worldwide to achieve their target tyre performances.

Düsseldorf, June 11, 2018 – Asahi Kasei has launched Thermylene® P11, a next-generation family of glass-reinforced polypropylene (PP) compounds with unprecedented strength. With the new material, the leading global supplier of high-performance thermoplastic compounds expands the performance envelope for conventional glass reinforced polypropylene design and opens opportunities for thinwall molding of interior and exterior automotive parts.

The Thermylene® P11 family of chemically coupled PP compounds, currently available in 30%, 40%, 45% and 50% glass loadings, delivers the highest tensile strength without sacrificing other performance attributes. It provides an optimum balance of properties and facilitates thinwall molding for a wide range of applications.

The new family of Thermylene® P11 compounds offers higher tensile strength at elevated temperature, greater room temperature tensile, and improved fatigue and creep resistance compared to the predecessor material family, Thermylene® P10. Thinwall molding is possible thanks to Thermylene® P11″s melt flow of 10-25 g/10 min – specifically tunable to customer needs.

„The Thermylene® P11 family is a step change improvement which enables European automotive OEMs and tier suppliers to fine tune the necessary performance without worrying about any compromise. Asahi Kasei has received strong interest in the new family of glass-filled PP compounds with material evaluations currently underway at leading OEMs and tier suppliers,“ said Vive Apte, Manager of Polyolefins R&D at Asahi Kasei.

Asahi Kasei is targeting a range of structural parts in the automotive and appliance markets. In interior automotive, key applications include door modules, center consoles, load floors, and instrument panels. Underhood automotive parts include fan shrouds, battery trays, front end modules, and grille shutters. In appliance, Thermlyene® P11 is targeted for heat-exposed dryer components such as lint trays.

Thermylene® P11 provides up to 40% improvement in measured tensile strength at 80°C and 120°C compared to conventional glass-filled PP. Thermylene® P11 GF40% boasts flexural modulus of 10,000 MPa, tensile strength of 125 MPa, and a heat distortion temperature of 155°C.

P11 PP compounds can also be processed at a lower temperature and a higher fill rate, resulting in energy and cycle time savings. Thinner wall thicknesses can be achieved in new designs due to the high tensile and flexural modulus properties. Due to the material“s high flow, parts can be packed more efficiently resulting in lower porosity/voids.

Science Research Technology

Efficient coating of O-rings

The new Rotamat system for small batches allows the efficient coating of work piece volumes from 2 to 15 liters.

Efficient coating of O-rings

The new Rotamat R 60 is suitable for coating of mass produced small parts made from elastomers/metal

At the DKT exhibition Walther Trowal presents the newly designed Rotamat R 60 for coating of mass-produced small parts like, for example, O-rings. This system was specifically developed for users who are increasingly switching to smaller batches and, generally, lower batch volumes. However, the R 60 offers all the features found in its larger „siblings“!

The new Rotamat R 60 is the first coating system on the market that allows efficient processing of work piece volumes between 2 and 15 liters. With a diameter of only 600 mm the drum is ideally suited for small batch volumes. The inclination of the drum is adjustable within a wide angle allowing its adjustment to different work piece geometries. It allows the intensive mixing of the parts in the drum and guarantees complete, optimum coverage by the spray nozzles.

With the new machine Walther Trowal takes into account that in connection with just-in-time requirements many companies generally place purchase orders in smaller work piece quantities.

Frank Siegel, sales manager „coating technology“ at Walther Trowal is now able to offer the right machine for practically every conceivable application: „Many of our customers want to coat small part batches but do not want to give up the high technical standard we have implemented in our larger units R 80 and R 90C. With the newly developed R 60 they can now efficiently coat small batches without having to invest in a larger machine.“

For the Rotamat R 60 the Trowal engineers have utilized the proven components of the larger machines: For example, the inlet and exhaust air system, the explosion protected LED lighting inside the drum and the mounting of the drum.

Here are some details of the innovative features

Precise control of the inlet air temperature

The measuring point for the inlet air temperature is immediately at the drum entry. Compared to measuring the temperature with a sensor behind the air heating unit the measurement is now much more direct allowing extremely precise temperature readings.

Eco-friendly operation

For typical applications – today 90% of all customers are using water-based paint – Walther Trowal supplies a specially adapted filtering system. For coating tasks with solvent-based paints the new R 60 – like with the bigger Rotamat units – can be equipped with a four stage exhaust air filtering system with a Papp filter, a filter mat and two pocket filters.

Low energy requirements

The capacity of the heating unit was adapted to the smaller drum diameter, resulting in considerably lower overall energy requirements. Depending on the technical characteristics of the work pieces and/or paint Walther Trowal can equip the machine with PID or pulse control for the heating unit. The result: Customers can also use paint types that do not allow going over or below certain operating temperatures.
