Product Description

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.

• 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
• Stock shapes -- for machining components
