PCTFE board

Polytrifluorochlorine ethylene It is called PCTFE for short. It is a polymer compound formed by polymerization of trifluoroethylene chloride. Low molecular weight is liquid or wax. High molecular weight is white solid or dispersion. Solid density 2.1~2.2. The melting point is 208~210 ℃. Heat resistance, acid resistance, alkali resistance (except halides), but not resistant to molten caustic soda and elemental fluorine. Soluble in aromatic hydrocarbon and carbon tetrachloride. Its chemical resistance is only inferior to that of polytetrafluoroethylene. Can be used as engineering plastic 。 Tensile strength 3.096~4.135 MPa (316~422 kgf/cm2). Generally used for chemical equipment and insulation with high performance requirements Cable , radio, capacitor and heat or low temperature resistant accessories, etc. Dispersion liquid is used to prepare anti-corrosion coating And film.
The synthesis methods of polytrifluorochloroethylene include bulk polymerization, solution polymerization and dispersion polymerization. It is prepared by free radical polymerization with peroxide as initiator.
Polytrifluoroethylene has excellent chemical stability, insulation and weather resistance. It can be used for a long time at - 196-125 ℃. Its mechanical strength and hardness are better than that of polytetrafluoroethylene. The film made of polytetrafluoroethylene has better transparency and lower air permeability.
Polytrifluoroethylene is suitable for use in contact with strong corrosive media, sealing and gasket materials of high-pressure systems, transparent materials of observation windows, and electrical insulation materials, etc., so it has special significance in chemical and atomic energy industries, but its price is more expensive than polytetrafluoroethylene. Low molecular weight polytrifluorochloroethylene has high density, excellent viscosity temperature characteristics and chemical corrosion resistance. It can be used as sealing fluid, grease and balance fluid of navigation gyroscope for highly corrosive media.
PCTFE has good rigidity, low temperature resistance and cold flow resistance. It is an ideal sealing material under low temperature and high pressure conditions, and has a special purpose in the high-tech field.
Application:
1. Sealing and gasket materials contacting with strong corrosive medium, high-pressure system, transparent materials of observation window, etc.
2. Electrical insulation materials, etc.
3. Low molecular weight PCTFE is used as sealing fluid, grease and balance fluid of navigation gyro for highly corrosive media.
