Describe

Polychlorotrifluoroethylene is abbreviated as PCTFE, a polymer compound formed by the polymerization of chlorotrifluoroethylene. Low molecular weight is liquid or waxy. The high molecular weight is a white solid or dispersion. It is resistant to heat, acid, alkali and organic solvents (except halides), but it is not resistant to molten caustic alkali and elemental fluorine. Soluble in aromatic hydrocarbons and carbon tetrachloride. The chemical resistance is second only to polytetrafluoroethylene. The dispersion is used to make anti-corrosion coatings and films.
Synthetic methods of polychlorotrifluoroethylene include bulk polymerization, solution polymerization and dispersion polymerization, etc. It is prepared by free radical polymerization with peroxide as the initiator. Can be used as engineering plastics.

Performance:

PCTFE 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 PTFE. The film made of it has better transparency and lower air permeability.

PCTFE is suitable for applications in contact with strong corrosive media, high-pressure system sealing and gasket materials, observation window transparent materials, and electrical insulating materials, etc., so it has special significance in the chemical and atomic energy industries, but its price is more expensive than PTFE . Low molecular weight polychlorotrifluoroethylene has high density, excellent viscosity-temperature characteristics and chemical resistance.
PCTFE has excellent rigidity, low temperature resistance, cold flow resistance, is an ideal sealing material under low temperature and high pressure conditions, and has special applications in the high-tech field.

Parameter

Application:

1. Contact with strong corrosive media, high-pressure system sealing and gasket materials, transparent materials for observation windows, etc.

2. Electrical insulation materials, etc.

3. Low-molecular-weight PCTFE is used as a sealing fluid for highly corrosive media, lubricating grease and balance fluid for navigation gyros. 4. Our company has a variety of specifications of PCTFE rods, pipes and plates. The specific specifications refer to the specifications of PTFE products (PCTFE products comply with the relevant enterprise standard Q/MSF03-01-2002).
