For e-powertrain applications a wide variety of sealing solutions are required, as there are multiple surfaces that must be sealed effectively. We have developed a number of solutions for these sealing challenges.
Datwyler has a leading role in producing materials and components in the most sustainable way possible, while advancing the mobility sector to become even more efficient and eco-friendly.
The Datwyler approach to sustainability of the materials used can be split into three key pillars: chemical compliance, supplier processes, and material research.
Datwyler, together with the development partner Empa, has developed and patented an industrial process for surface modification of microfibrillated cellulose (MFC).
Datwyler has developed thermal interface materials focusing on stand-alone gasket solutions for battery systems.
As experts in various aspects of material development, you can have confidence in us to deliver solutions that are perfectly aligned with your specific needs and requirements. Decades of knowledge and experience has been curated and continuously evolved to ensure you have access to cutting-edge materials – with every element of the process controlled and carried out in-house. From the raw material stage, where we create individual compounds, through to complex recipe development, formulation and in-house mixing, we materialize ideas for a safer, smarter and more sustainable world.
The conflicting requirements for materials in terms of temperature spectrum, mechanical stress, media resistance and other criteria are constantly increasing with modern systems and applications, and our compounds must increasingly push both physical and chemical boundaries to deliver the functionality and reliability you need.
Accountability is fundamental, and our co-engineering approach ensures we have an in-depth understanding of your goals and the ability to support you throughout the lifecycle of a product. Drawing on expertise in areas such as simulation, engineering, surface technology and chemical compliance, your material will be fully analyzed ahead of both production and application, ensuring any amendments to the process or specific part geometries can be made well in advance of serial production.
This materials science and analytical expertise is geared specifically towards Datwyler products and formulations, which span the material landscape. In addition to focusing on elastomeric compounds for over 100 years, our capabilities extend to thermoplastics (TPE), liquid silicon rubber (LSR), specialist fillers and coatings, metal inserts, intelligent sealing solutions and thermally conductive compounds – amongst many others.
From our centers of excellence, every element of a material can be customized to specification, and our network of in-house experts are positioned around the globe to ensure you have direct support at a personal level wherever you are located. Working across a wide range of applications, we have dedicated experts in polymer-based materials of all compositions. From LSR and TPE, to Bonding Agents and multi-component parts, the entire spectrum is covered at the highest possible level.
Optimizing material surfaces is vitally important, as achieving and maintaining good bonding between inserts and rubber parts, meeting specifications, and minimizing deviations creates the highest quality end results. At our Technology & Innovation (T&I) Labs in Switzerland, we have created a dedicated team of experts, with state-of-the-art laboratory equipment and conditions, to ensure both processes and outcomes deliver for you.
Our T&I Labs use the latest technology for processes such as cleaning, spraying and surface activation, featuring a pilot ultrasonic cleaning plant for inserts, for example, a pilot phosphating plant for the preparation of inserts, and various spraying booths for conventional or ultrasonic application of bonding agent.
For the healthcare market specifically, we have dedicated capabilities in areas such as fluoropolymer coatings, with the ability to test new coatings and new designs to ensure that a barrier against extractables and leachables is achieved. Our Technology & Innovation (T&I) Labs in Belgium feature mini-coaters, hand-held spray booths and X-Y spray robots that can reproduce a coating process on a small scale, and validate designs. Our unique, fully coated products deliver low friction coefficients, and we can characterize the effectiveness of the barrier against extractables and leachables directly in the same lab. Polysisoprene, used in medical applications, can also be chlorinated to reduce the stickiness of the rubber and therefore improve machinability of the pieces.
We have invested heavily in the latest analytical equipment, including chromatographical techniques like ICP and GC/MS, and also SEM-EDX, and where additional analysis is required we have partnerships with industry leading external collaborators, such as a.o. Nelson Labs in Belgium. Each element of the process is managed in-house on your behalf, ensuring you maintain a single point of contact throughout.
We understand the critical importance of testing and analysis in terms of the physical and chemical properties of materials, as well as the functional performance of our products; whether within the bulk or at the surface. Every project will have its unique requirements, and we have developed our in-house Technology & Innovation laboratories to deliver the capabilities you need. Supporting from our different Technology & Innovation Labs worldwide, you benefit from our dedicated experts and their ability to perform the entire spectrum of testing in-house. Whether it is material developers formulating compounds, engineers creating the prototypes, or lab experts testing properties, we work together to find the very best solutions to your challenges.
Since our T&I Labs are entirely in-house, we offer complete independence, transparency, and flexibility at every stage of the development process – from material development to application performance testing. Together, we will drive the development of breakthrough, innovative products and also the improvement of existing products through advanced root cause analysis. By combining our extensive material expertise with the capabilities of the labs it is possible to analyze the interaction between materials, to optimize their properties and to control the processes for the highest quality outcomes.
Our capabilities and processes ensure you have the peace of mind that comes with achieving regulatory compliance to the highest level, while our co-engineering approach enables us to identify areas where non-standard testing may add further value. We are able to develop and execute bespoke tests to very specific parameters, drawing on our comprehensive portfolio to ensure material combinations are optimal for every application. In addition, our laboratories in different geographical locations collaborate, giving you the global support necessary to achieve consistency in different market areas.
The substances used across our material portfolio are subject to the highest levels of regulatory compliance, like a.o. REACH and CLP, and we therefore take a proactive approach to ensuring there are no surprises for you in terms of business continuity. Based on historical data, we monitor our portfolio closely to ensure any substances with the potential for ‘at risk’ classification in the future are engineered out of our formulations, while for new material innovations we ensure all compounds used are at the lowest possible risk levels by working closely with our material development experts.
As a technical advisor to groups such as the ETRMA (European Tyre & Rubber Manufacturers’ Association) and the WDK (Wirtschaftsverband der Deutschen Kautschukindustrie), we play an active role in the decision-making process where classifications of materials are concerned. This early awareness enables us to develop, validate and qualify substitute materials in partnership with you before any risk of supply chain disruption is experienced.
Any identified risk is forensically examined, and our chemical compliance teams collaborate closely with our material scientists to ensure our solutions are future-proofed. As one of the few manufacturers of elastomer products, we consistently and uniformly implement the findings of our systematic chemical regulatory compliance at all plants worldwide.

As applications evolve and classifications change, our experts are focused on identifying alternative raw materials to produce more sustainable compounds, as well as developing specialist compounds in-house – such as our own sustainable cellulose filler, for example. Life Cycle Assessment (LCA) is part of the Eco-Design approach we apply to new developments, which in turn influences the decision-making process where new compounds are in development. Chemically compliant, sustainable materials will create compounds with low LCA scores, and our expertise ensures they do so with zero compromises on quality or performance.
