PCTFE (Polychlorotrifluoroethylene)

• PCTFE, combines physical and mechanical properties, non flammability, chemical resistance, near-zero moisture absorption and excellent electrical properties not found in any other thermoplastic fluoropolymer that also performs well in a temperature range of -400° F to 400° F. PCTFE also has high compressive strength, an exceptional resistance to cold flow and is optically transparent. Because PCTFE is a highly fluorinated resin, it is nonflammable and resists most corrosive chemicals.

Preferred Fields:
Cryogenic and chemical processing components, seals and gaskets, aerospace valve seats, pump parts, impellers, diaphragms, and plugs. Laboratory instruments, nuclear service/high radiation exposure, liquid oxygen and liquid nitrogen valve linings.
 

Characteristics:

• Dimensionally stable, rigid, and resistant to cold flow
• Very low gas permeation and outgassing
• Near zero moisture absorbtion
• Excellent chemical resistance
• High compression strength
• Low deformation under load
• Non-flammable
• Temperature range: -400° to 380°F
• Radiation Resistance
