PTFE material - Polytetrafluoroethylene

PTFE material (with the chemical name polytetrafluoroethylene, commonly referred to as Teflon^® plastic) is a semi-crystalline fluoropolymer with many unique properties. This fluoropolymer offers exceptionally high thermal stability, chemical resistance, and corrosion resistance, as well as a high melting point (-200 to 260 °C, briefly also up to 300 °C).

In addition, PTFE products have excellent sliding properties, excellent electrical resistance and a non-stick surface. In contrast to other plastics, however, they have low mechanical strength and a high specific density. With these qualities, PTFE plastic is commonly manufactured into rollers, seals, and seal rings. To improve the mechanical properties, the PTFE polymer can be reinforced with additives such as glass fibres, carbon, bronze or even with polyimide.

As an experienced PTFE supplier and manufacturer, Ensinger is in the position to offer expert solutions regardless of whether your application involves injection molded PTFE parts or PTFE machined parts. We also have the ability to supply stock shapes if you prefer to do your own PTFE CNC machining.

Polytetrafluoroethylene is often formed into semi finished products using a compression process and then machined with cutting/machining tools. Ensinger offers PTFE shapes under the brand name TECAFLON PTFE and the TECASINT group 8000. The following shapes are available:

The Ensinger TECAFLON family of PTFE plastics offer the following modifications:
