polychlorotrifluoroetyleeni

Polychlorotrifluoroethylene, often abbreviated as PCTFE, is a synthetic fluoropolymer. It is a thermoplastic known for its excellent chemical resistance, low coefficient of friction, and good mechanical properties. PCTFE is a homopolymer derived from the polymerization of chlorotrifluoroethylene monomer. Its molecular structure features a repeating unit of (-CF2-CFCl-).

The unique combination of chlorine and fluorine atoms in its structure provides PCTFE with notable characteristics. It exhibits very low permeability to gases and moisture, making it a valuable material for barrier applications. PCTFE is also resistant to a wide range of chemicals, including strong acids and bases, as well as many organic solvents. It possesses a low dielectric constant and excellent electrical insulation properties.

PCTFE finds application in various industries due to its desirable properties. It is used in the manufacturing of seals, gaskets, bearings, and valve components where chemical resistance and low friction are essential. Its barrier properties make it suitable for packaging sensitive pharmaceuticals and electronics. Additionally, PCTFE can be processed using conventional thermoplastic methods like extrusion and injection molding.
