PCTFE (PolyChloroTriFluoroEthylene) is a fluorocarbon based polymer and is frequently abbreviated as PCTFE. PCTFE combines physical and mechanical properties, non-flammability, chemical resistance, near zero moisture absorption and excellent electrical properties not found in any other thermoplastic fluropolymer. This material also has high compressive strength, an exceptional resistance to cold flow, and performs well in a temperature range of -400° F to 400°F.
PCTFE maintains an outstanding electrical-insulating capability through thermal cycling and in high humidity environments. This material’s high compressive strength and dimensional stability make it a good choice for structural material, while its low outgassing rate (0.01% TML, 0.00% CVCM, 0.00% WVR when tested per ASTM E-595-90), and permeability make PCTFE a great choice for laboratory, aerospace, flight applications, and instrumentation.
