Product Description

 

Product Description

Kel-F type polychlorotrifluorethyene, is the homopolymer of chlorotrifluorethylene. Kel-F, or PCTFE, offers the unique combination of physical and mechanical properties, nonflammability, high optical transparency, chemical resistance, near zero moisture, and excellent electrical properties that cannot be found in other thermoplastic fluoropolymers. It has a useful temperature range of -240 degrees C (-400 degrees F) to +200 degrees

What is PCTFE / 3M Kel-F?

PCTFE was developed and manufactured by the 3M Company under the Brand name of Kel-F. In 1995, the 3M Company discontinued the manufacturing of the PCTFE materials. 

PCTFE Plate, tube and rod 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.

• Perfect material for cryogenic applications
• Dimensionally stable over a wide temperature range
• Extremely low gas permeability.
• Excellent resistance to creep.
• Working temperature from -200°C to +120˚C
