Polychlorotrifluoroethylene - PCTFE
General Description : An expensive, semi crystalline, melt processable thermoplastic. It has a chemical structure similar to that of PTFE but with one chlorine atom substituted for a fluorine atom in the repeat group. PCTFE offers a unique combination of physical and mechanical properties, non-flammability, high optical transparency, chemical resistance, near zero moisture absorption and excellent electrical properties. PCTFE also has extremely low outgassing (0.01% TML, 0.00% CVCM, 0.00% WVR when tested per ASTM E-595-90) and so is suitable for use in aerospace and flight applications. Industrial applications include chemical apparatus, process equipment, cryogenic applications, valve seats, seals, gaskets, sight glasses (special process), laboratory equipment, medical equipment, gears, cams and bearings.
