PCTFE,also known as kel-f, is a kind of perfect sealing material under cryogenic and high pressure conditions.It has excellent rigidity, low temperature resistance, cryogenic fluid resistance and good size stability.
• 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 oxygen etc.),semiconductor,chemical,pharmaceutical,aerospace and other relevant sealing area.
