Our rubber engineering specialists are happy to take on the challenge. Do you have an issue to which there is no ready-made answer? That is precisely where our strength lies. Over the past 16 years, we have built up an unparalleled wealth of specialist knowledge and experience. With a lot of craftsmanship, experience and feeling, we create groundbreaking rubber solutions for the most demanding sectors.

Our custom-made rubber seal products can meet the highest requirements and perform under extreme conditions. For example, should the final product be able to withstand very low or high temperatures? Is it an electrically conductive or insulating product? And does it have to be resistant to liquids, oil or gas? We always first carefully map out your situation and, based on the circumstances, start working with the basis of the product: the rubber compound. A unique recipe that we develop in-house.
