PCTFE (formerly known as Kel-F)

PCTFE is a homopolymer of chlorotrifluoroethylene, which is a homopolymer with properties not usually found in other fluoropolymer resins. Some of these properties include compressive strength and an exceptional resistance to cold flow.

  • High compressive strength
  • Non-flammable and relatively unaffected by most corrosive chemicals.
  • Excellent elastic memory. Deforms slightly under load but will recover when the load is removed. As with most thermoplastics, its physical strength will decrease as the temperature increases.
  • Maintains its excellent electrical insulating capability through thermal cycling and high humidity
  • High optical transmittance, low haze and low gas and moisture vapor transmission. Non-wetting and zero moisture absorption. Dimensional stability unaffected by high humidity and under prolonged immersion in water.
  • Excellent cut-through resistance remains flexible, and can be bent without cracking at extremely low temperatures.
