Engineering plastics

Where acids, alkalis or solvents attack metal, we manufacture sealing rings, housings and components from engineering plastics. Which plastic fits depends on medium, temperature and pressure.

PlasticProperties
PTFEChemically resistant to almost all media, very low friction
PEEKChemically resistant, plus high strength and temperature resistance
PEEconomical alternative where its resistance is sufficient
PPResistant to many acids and alkalis, economical, for moderate temperatures

Other plastics on request.
