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.
