PCTFE IS WIDELY USED FOR:

• 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

PERFORMANCE CHARACTERISTICS:

• Dimensionally stable, rigid, and resistant
  to cold flow
• Very low gas permeation and outgassing
• Near zero moisture absorption
• Excellent chemical resistance

The main field of application of PCTFE is cryogenics due to the fact that it is the fluoropolymer that best retains its mechanical properties at extremely low temperatures and is therefore the least fragile of the fluoropolymers.

PCTFE is incompatible with alkaline metals and in some cases with organic amines. Its use is not recommended at temperatures above 150°C.

PCTFE rod is recommended for cryogenic application and handling of gases. PCTFE rod has better mechanical properties than other fluoropolymers and low permeability.
