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 airflowresistance.
Key Properties
Near-zero moisture absorption
Excellent performance under a wide temperature range
Resists most corrosive chemicals
Excellent electrical-insulating properties
Extremely low outgassing
Application:
- Cryogenic applications( seals for Cryogenic Valve etc.)
- Excellent resistance to cold flow
- Dimensional stability through a wide temperature range
- Rigidity
- Extremely low gas permeability
- Extremely low moisture absorption
- Good transparency
PCTFE is a good choice for instrumentation, laboratory, aerospace and flight applications. Other common applications include cryogenics, valves, seals, and film for food and pharmaceutical packaging.
