Expertise put in a nutshell

Even after 25 years in elastomer technology, we are constantly developing, combining theoretical expertise with the practical experiences gained in our daily workEven after 25 years in elastomer technology, we are constantly developing, combining theoretical expertise with the practical experiences gained in our daily work.

We share our knowledge in numerous technical reports and publications and explain elastomer and application knowledge to you in a clear and transparent manner.

In the technical reports, we provide you with information about important test methods for elastomers and show you developments and trends in test technology. We explain how individual test methods can be used sensibly and where they find their limits.
