Teflon plastic family including PFA, PTFE, FEP and ETFE, the materials seperate double properties, extruded and molding, extrusion main use for wire and cable ,another is for Injection molding, the common character is high temperature and chemical resistant. Teflon plastic is a popular selection during our work find solutions for clients because of them excellent properties.
PFA plastic (Polytetrafluoro ethylene) is a copolymer of small amount of perfluoropropyl perfluoro vinyl ether and polytetrafluoro ethylene. The melt adhesion is enhanced, the viscosity of the solution decreases, and the performance does not change compared with that of polytetrafluoro ethylene. This resin can be directly used in ordinary thermoplastic molding process into products. Suitable for making corrosion-resistant parts, wear-resistant wear parts, seals, insulation and medical equipment parts, high temperature wire, cable insulation, anti-corrosion equipment, sealing materials, valve bushings, and chemical containers.
Polyfluoroethylene propylene resin with PTFE and similar properties, but also a good thermoplastic processing technology, which makes it an important substitute for polytetrafluoroethylene material. F-46 in the production of wire and cable widely used in high temperature and high frequency used in the transmission of electronic equipment, the computer’s internal cable, the aviation universe wire, and other special purpose installation lines, oil logging cables, submersible motor winding wire , Micro-motor lead wires and so on.
Polytetrafluoroethene, commonly known as “non-stick coating” or “easy to clean wok material”; is a fluorine-substituted polyethylene used in all the hydrogen atoms of synthetic synthetic polymer materials. This material has acid Anti-alkali, anti-organic solvent characteristics, almost insoluble in all solvents. At the same time, PTFE has high temperature characteristics, its friction coefficient is very low, so can be used for lubrication, Wok and the inner layer of the ideal coating.
ETFE (F-40) Fluoroplastics from the United States DuPont and Japan Asahi Glass, mainly used in anti-corrosion lining. The material has the corrosion resistance of polytetrafluoroethylene, while the metal has a unique adhesion characteristics, to overcome the non-adhesive Teflon metal defects, coupled with its average linear expansion coefficient close to the carbon steel line Expansion coefficient, so that ETFE (F-40) and the metal as the ideal composite material, with excellent resistance to negative pressure characteristics.
