High-Performance Plastics

PTFE high-performance plastics are our strength. They are used in demanding applications — when reliability and safety have priority and there is no alternative to the outstanding material properties. This is precisely why we manufacture PTFE semi-finished products [press-sintered parts or extrudates] and PTFE molded parts as well as composite parts made of PFA and metal with precision and technical expertise. We are also experienced in processing other fluorinated polymers such as PVDF and PCTFE, engineering plastics such as PE-UHMW, PEEK and POM. Moulded parts such as gasket inserts, seat rings, bellows, bearing bushes and cover seals are manufactured according to customer specifications, drawings, or samples.

In order to be able to react flexibly and quickly to individual customer requirements, we stock almost 20 custom compounds in addition to the pure, virginal PTFE and the more diffusion-tight Dyneon TFM®. Through compounding, the already very advantageous properties of PTFE can be modified and improved for special requirements. Organic or inorganic substances such as graphite, glass fiber or quartz are added to the material for this purpose.

The material properties of PTFE include: #

  • Heat resistance from -268 to +260 °C
  • Chemical resistance, almost universal, even against aggressive media
  • Low coefficient of friction, high elongation at break and flexural fatigue strength
  • No material adhesion due to low surface tension
  • Physiologically harmless, even in continuous operation up to 260 °C
  • insensitivity to weathering and high UV stability
