PCTFE
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 contains 49% fluorine. 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:
1. Sealing gaskets, parts under high pressure, high strength and low temperature condition
2. Protective layer against moisture
3. Coating and prefabricated liner for chemical applications
4. Transparent lens, tubes, valves, chemical tank lining, O-rings, seals and gaskets
