Development of our product range

In the first decades there were mostly manufactured products for daily use. Industrial products were added to the product range little by little.

At the beginning of the 1990s the product range increasingly transferred to the automotive sector.

At the beginning of the 2020s it was started to intensify the production of parts for the dairy and food industry.

Rubber compounds

Up to 500 tons of various rubber compounds are used for the production of rubber and rubber metal parts in our company per year.

Types of elastomer:

  • NR, BR, SBR, EPDM, Silicone (HTV), IR, CSM, ECO, AEM and appropriate copolymers
  • Shore hardnesses from 35 ShA to 95 ShA
