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.

Plastics for PTFE Gaskets and other gasket solutions

In our production we use plastic semi-finished products and panels from various renowned manufacturers such as Garlock, Frenzelit or Klinger.
We use the material PTFE, which is also colloquially known under the trade name Teflon®, in standard delivery standards as plates, foils and solid rods. The particularly chemical-resistant plastic impresses with its high resistance in temperature ranges from -200 to +250 °C. In our production, the thermoplastic is primarily used for PTFE seals and membranes as well as turned parts.

We would be happy to provide you with individual advice on suitable plastic solutions for your areas of application.
