Manufacture of rubber mixtures

The rubber mixtures of our products are created by our cooperation partners in accordance with our requirements. This enables us to use a large portfolio of different rubber mixtures such as EPDM, NBR, FKM, FFKM. By specifying requirements and quality controls, we intervene early in the manufacturing process and can guarantee consistently excellent quality.

The production of large series is mainly carried out in Germany, Sweden, Poland and England.
