The fluoropolymer PCTFE (polychlorotrifluoroethylene), often known as Kel-F® or Neoflon®, is a fluoropolymer with exceptional strength, stiffness, and dimensional stability.
Chemical resistance, radiation resistance, and flammability are all outstanding properties of PCTFE. The temperature range for this material is -400°F to 380°F. PCTFE has the lowest coefficient of thermal expansion of any unfilled fluoropolymer and is resistant to cold flow. When dimensional stability is important, these properties make it an ideal choice.
When chemical resistance, a wide working temperature range, and low flammability are required, PCTFE is frequently utilised in aircraft applications. It has a very high resistance to weathering.
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
- Dimensionally stable, rigid, and resistant to cold flow
- Very low gas permeation and outgassing
- Near zero moisture absorption
- Excellent chemical resistance
- Useful temperature range: –400°F to 380°F
- Radiation resistance
