Polytetrafluoroethylene is the most important variety of fluoroplastics. It has excellent chemical stability, weather resistance, electrical insulation, flame resistance, outstanding surface non adhesion, extremely low friction coefficient, and a wide range of service temperatures. It can be used as wear-resistant, corrosion resistant, sealing, insulation, anti adhesion, and high and low temperature resistant materials, and is suitable for long-term work in the temperature range of -80-250C. Tetrafluoroethylene ethylene copolymer, known as fluoroplastic 40, is the lowest density of fluoroplastic (1.71-1.75g/cm3). It has both the radiation resistance of polyethylene and the corrosion resistance of tetrafluoroethylene, and can resist the corrosion of acid, alkali and salt aqueous solutions. It does not dissolve or swell in solvent. It is used as anti-corrosion, electrical insulation and radiation resistant parts in chemical, machinery, electrical appliances, atomic energy and other industries, with long-term service temperature of - 60-180 Cand short-term service temperature of 230 ℃. The tetrafluoroethylene hexafluoropropylene copolymer is composed of about 82% tetrafluoroethylene and about 18% hexafluoropropylene. Its properties and uses are similar to those of tetrachloroethylene, but it can be molded and processed by general thermoplastic molding processing methods, and is suitable for working at - 85-205C. Chlorotrifluoroethylene ethylene copolymer is called fluoroplastic 30. It has both the mechanical strength of nylon, the corrosion resistance of fluoroplastic and the molding performance of high-density polyethylene. It has good adhesion with metals, can be welded and fused by itself, and has excellent ultraviolet and infrared transmission and gas resistance properties. It is suitable for making seals, mechanical parts, low-frequency insulation products working under strong current, wet or corrosive media, etc FEP,PFA,PCTFE,PVDF,ETFE,PVF,PTFE Mianyang Prochema Commercial Co.,Ltd. , https://www.gustek.com
