PCTFE Kel-F, Neoflon M-400H PCTFE
Kel-F type Neoflon M 400H PCTFE, 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 and sold the rights to Daikin Industries Ltd. Who now produces the resin under the brand name of Neoflon PCTFE grade M-400H. The actual 3M Kel-F plastic is no longer available in the marketplace.
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.
