PCTFE Kel-F®

Kel-F® PCTFE Key Facts

Kel-F” 81 Plastic PCTFE is the homopolyer of chlorotrifluoroethylene.

This polymer structure imparts the properties that make Kel-F” 81 Plastic PCTFE a truly unique engineering thermoplastic. A complete family of powdered and pelletized polymers is covered by the product line. These products are designed for the production of high­ performance parts by the various conventional thermoplastic processing techniques currently used in the plastic industry.

Since Kel-F” 81 Plastic PCTFE is a versatile material whose properties may be modified over a wide range depending upon fabrication conditions, careful specification of pertinent properties for a given application is advisable.

Kel-F” 81 Plastic PCTFE offers the unique combination of physical and mechanical properties, non-flammability, high optical transparency, chemical resistance, near zero moisture absorption and excellent electrical properties that cannot be found in any other thermoplastic fluoropolymer with a useful temperature range of -240°C (-400°F) to +200°C (400°F).

Kel-F” 81 Plastic PCTFE is available in products which conform to ASTM D-1430, Type I, Grade I, Class B, and Class C.
