PCTFE, or poly(chlorotrifluoroethylene), is a polymer compound formed by the polymerization of chlorotrifluoroethylene. Low molecular weight PCTFE is a liquid or waxy substance, while high molecular weight PCTFE appears as a white solid or dispersion. The solid density ranges from 2.1 to 2.2. The melting point is between 208 and 210°C. It exhibits resistance to heat, acids, alkalis, and organic solvents (except halides), but is not resistant to molten caustic alkalis and elemental fluorine. It is soluble in aromatic hydrocarbons. Its chemical resistance properties are second only to those of polytetrafluoroethylene (PTFE). PCTFE can be used as an engineering plastic. The tensile strength ranges from 3.096 to 4.135 MPa (316 to 422 kgf/cm²). It is commonly used in chemical equipment requiring high performance, insulation cables, radio components, capacitors, and heat or low-temperature resistant fittings, among others. The dispersion is used for anti-corrosion coatings and films. The synthesis methods for PCTFE include bulk polymerization, solution polymerization, and dispersion polymerization, using peroxides as initiators for free radical polymerization. PCTFE possesses excellent chemical stability, insulation properties, and weather resistance, suitable for long-term use at temperatures ranging from -196 to 125°C. Its mechanical strength and hardness exceed those of PTFE, and when made into films, it has good transparency and low gas permeability rates. PCTFE is suitable for applications involving contact with highly corrosive media, sealing and gasket materials in high-pressure systems, transparent materials for observation windows, and electrical insulation materials. Therefore, it has special significance in the chemical and atomic energy industries, although its price is higher than that of PTFE. Low molecular weight PCTFE has high density, excellent viscosity-temperature characteristics, and chemical corrosion resistance, making it suitable as a sealing liquid, lubricant, and balance fluid for navigation gyroscopes in high-corrosion environments. Applications: 1. Sealing and gasket materials for contact with highly corrosive media and high-pressure systems, and transparent materials for observation windows. 2. Electrical insulation materials. 3. Low molecular weight PCTFE as sealing liquids, lubricants, and balance fluids for navigation gyroscopes in highly corrosive media. Our company offers PCTFE rods, pipes, sheets, seals, gaskets, valve seats, and other products in various specifications. For specific specifications, refer to PTFE product specifications (PCTFE products comply with relevant enterprise standards). PCTFE Product Specifications: Project: Density (g/cm³): 2.10-2.18 Tensile Strength (MPa): ≥ 30 Elongation at Break (%): ≥ 20 Continuous Use High Temperature (°C): -200 to 150 Dielectric Strength (kV/mm): ≥ 15
