Product Description

Product Description

PCTFE is a kind of perfect sealing material under low temperature, high vacuum system and high pressure working conditions. It has excellent rigidity, low temperature resistance, cryogenic fluid resistance, and airflow resistance.

Main Properties & Application

• Perfect material for cryogenic applications
• Dimensionally stable over a wide temperature range
• Extremely low gas permeability.
• Excellent resistance to creep.
• Working temperature from -200°C to +120˚C

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

Application of PCTFE tube/rod

• Cryogenic applications -- super-cold refrigeration components
• Vacuum insulated piping for Liquid Nitrogen or Liquid Oxygen
• Valves -- seats, stems, seals (Butterfly Valves for cryogenic applications were developed for large pipes which are used to transport cryogenic fluids).
• Seals for lip seals with spring energizer, o-rings, v-rings, special construction seals
• Compressors & pumps
• Gaskets -- pressure, diaphragm, liquid gauge seals, fluid handling
• Bearings -- sleeve & thrust
