PCTFE(Polychlorotrifluoroethylene) is a fluorocarbon based polymer. It offers the unique combination of physical and mechanical properties, non flammability, low permeation capability to moisture and steam atmosphere compared to other plastics. The heat resistance and chemical resistance capability is less than PFA and FEP, however, mechnical characteristics(especially hardness) are superior. It is suitable for utilizing in temperature range of -200℃～150℃,specially for cryogenic applications such as oxygen, hydrogen, nitrogen and more. PCTFE have a very strong resistance performance to low temperature.
2. Main properties:
- Stress-crack resistance
- High mechanical strength and low shrinkage rate at low temperatures providing excellent stability for valve seats.
- Excellent stability at low temperatures
- Good machining properties
- Excellent chemical resistance to all inorganic corrosive liquids
- Practically zero moisture absorption
- Excellent electrical properties maintained in high humidity conditions
- Maximum temperature for continuous use: 248 F (120 C)
- Melting point: Approx. 410 F
- These characteristics are maintained over a working range of
-400 deg. F to 248 deg. F (-240 deg. C to 120 deg. C).
