Major Features of PCTFE

  • Gas Barrier Properties ImageGas Barrier Properties
    PCTFE has excellent gas permeability among fluoropolymers and engineering plastics, and is the best material in terms of moisture resistance (water vapor permeability).
  • Mechanical Strength ImageMechanical Strength
    PCTFE is harder and has more excellent dimensional stability and impact resistance, compared to other fluoropolymers
  • Excellent Low-Temperature Properties ImageExcellent Low-Temperature Properties
    PCTFE offers a high mechanical strength even at low temperatures and demonstrates excellent low-temperature properties, such as being used as a valve seat for liquid helium.

Major Applications of PCTFE

  • Components For Semiconductor Manufacturing Equipment
  • Semiconductor Valves
  • Gas Valves
  • Medical Valves
  • Low-Temperature Valves for Petrochemicals
