Material range

Different technical applications of moulded-rubber articles also require different materials. Selection is made according to customer requirements and on the basis of our experience.

With our own development and about 2,000 formulations, we can react flexibly and quickly to all customer requests. Here, we take into account customer-specific standards and regulations as well as country-specific approvals. We can process all currently known elastomers.
