Description
With excellent rigidity, low temperature and cold flow resistance, PCTFE (PolyChloroTriFluoroEthylene) is an ideal sealing material under the condition of low temperature and high pressure in enormous high-tech fields.
Features:
PCTFE ,it has high compressive strength, high hardness, creep resistance, lowest moisture vapor transmission rate and very low gas permeance rate. Infrared, ultraviolet and visible lights can easily penetrate through PCTFE.
1. Excellent electrical properties
2. Wide Temperature Range: -200 Celcius degree to +150 Celcius degree
3. Extremely Low Outgassing
4. Near Zero Moisture Absorption
5. Good Mechanical Properties
6. Non-flammability
Typical Applications for PCTFE hollow bar
- 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
