Poly three vinyl fluoride PCTFE, polymer compound composed of three fluoride vinyl chloride through polymerization. Solid density 2.1~2.2. The melting point of 208~210℃. Resistant to heat, acid and alkali (except halides), but not to molten caustic soda and the element fluorine. Chemical resistance is second only to PTFE. Tensile strength 3.096~4.135 mpa (316~422 kg force/cm²). Generally used in chemical equipment with high performance requirements, insulated cables, radio equipment, capacitors and heat or low temperature accessories.

PCTFE with excellent chemical stability, insulation and weather resistance, can be in 196 ~ 125 ℃ using for a long time, mechanical strength and hardness is better than PTFE.

Poly three vinyl chloride fluoride is suitable for sealing in highly corrosive medium and high pressure system, so it has special significance in chemical industry and atomic energy industry, but it is more expensive than PTFE.

With excellent rigidity, low temperature resistance and cold flow resistance, PCTFE is an ideal sealing material under low temperature and high pressure conditions and has a special use in the high-tech field.

Application:

PCTFE in valve sealing, mainly used in contact with strong corrosive media, high pressure and low temperature sealing.
