Technical plastics

Since 1878 we design and realize gaskets made of metals and plastics according to your specific requirements. In addition to PTFE gaskets made of polytetrafluoroethylene we also supply gaskets made of polyvinyl chloride (PVC), polypropylene (PP) and polycarbonate (PC). Get an overview of the specific properties of the materials we use.
