Background

PCTFE SHEETS

Description:

PCTFE is widely used for seals in the condition of low temperature with high pressure (gas, liquid nitrogen, liquid oxygen etc.) semiconductor, cryogenics, chemicals, pharmaceutical, aerospace and high pressure relevant sealing area.



Transparent PCTFE Sheets features:

  • Excellent chemical resistance
  • Resistant to cold flow
  • Good mechanical strength
  • Very low gas permeation
  • Good dimensional stability
  • Near zero moisture absorption
  • High limiting oxygen index (LOI)
  • Radiation resistance
  • High transparency
  • Liquid oxygen compatible

Application:

  • Cryogenic valves & pipeline seals
  • Semiconductor application
  • Special gas sealing materials
  • Chemical analysis instruments
  • Chemical fluids & cryogenic equipment
  • Aerospace components
  • Medical & Pharmaceutical
  • Nuclear applications
