PCTFE material (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 fluoropolymer. 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.
PCTFE material is commonly selected for demanding industrial applications because of its stable physical and chemical properties. Compared to many engineered plastics, PCTFE offers extremely low moisture absorption, helping components maintain dimensional consistency in controlled or sensitive environments.
Additional advantages include:
These performance benefits make PCTFE material suitable for applications where reliability and precision are critical. Components used in cryogenic systems, semiconductor processing equipment, and chemical handling systems often require materials capable of maintaining stability under changing operating conditions.
