PCTFE (PolyChloroTriFluoroEthylene)
Industry Tradenames: Kel-F . Neoflon . Diakon . Chemfluor
Material Description
PolyChloroTriFluoroEthylene, abbreviated PCTFE, is a fluorocarbon-based polymer offering excellent electrical properties, chemical resistance, nonflammability, and near zero moisture absorption. With a useful temperature range of -400°F to +400°F (-240 to +204°C) and an outgassing of 0.01% TML, 0.00% CVCM, 0.00% WVR when tested per ASTM E-595-90, PCTFE is the only thermoplastic fluoropolymer with these characteristics that is also suitable for aerospace applications.
