low temperature resistanace anticorrosive pctfe tube
PCTFE material = POLYfluoroethylene chloride referred to as PCTFE, by the polymerization of polyfluoroethylene chloride from the polymer compounds. Low molecular weight is liquid or waxy. The higher molecular weight is a white solid or dispersion. Solid density 2.1~2.2. The melting point of 208 ~ 210 ℃. Resistant to heat, acid, alkali and organic solvents (except halides), but not to molten caustic soda and elemental fluorine. Soluble in aromatic hydrocarbon and carbon tetrachloride. Chemical resistance is second only to ptfe. Can be used as engineering plastics. Tensile strength 3.096~4.135 mpa (316~422 kg force/cm 2). Generally used in chemical equipment with high performance requirements, insulated cables, radio, capacitance products and heat or low temperature resistant accessories. Dispersants are used to make anticorrosive coatings and films.
The synthesis methods of POLYtrifluoroethylene include bulk polymerization, solution polymerization and dispersion polymerization, etc., which are prepared by radical polymerization with peroxide as initiator.
Polytrifluoroethylene has excellent chemical stability, insulation and weather resistance, and can be used at -196 ~ 125℃ for a long time. Its mechanical strength and hardness are better than that of polytetrafluoroethylene. The film has better transparency and lower permeability.
Polytrifluoroethylene is suitable for use in contact with strong corrosive media, high pressure system sealing and liner materials, transparent observation window materials, as well as electrical insulation materials, etc., so in the chemical industry, atomic energy industry has special significance, but its price is more expensive than ptFE. Low molecular weight POLYtrifluoroethylene has high density, excellent viscosity-temperature characteristics and chemical corrosion resistance. It can be used as sealing liquid, lubricating grease and balance liquid of navigation gyro, etc.
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 special applications in the high-tech field.
1. Contact with highly corrosive media, sealing and liner materials of high pressure system, transparent materials of observation window, etc
2. Electrical insulation materials, etc.
3. Low molecular weight PCTFE plate (polytrifluoroethylene material plate) is used as the sealing liquid of highly corrosive medium, lubricating grease and the balance liquid of navigation gyro, etc.
4. It can be widely used as corroding structural material, anti-corrosion lining of equipment, transparent viewing mirror, vacuum sealing material, electronic and electrical components, motor instrument parts, electrical insulation material, etc.
Applicable industry: PCTFE is widely used in low temperature and high pressure sealing parts (liquid nitrogen, liquid oxygen, etc.), semiconductor, chemical, pharmaceutical, aerospace and other related sealing fields.
