What is the FEP Material
- Jun 06, 2018 -

     Ethylene fluoride propylene copolymer (perfluoroethylene propylene copolymer) was synthesized by copolymerization of tetrafluoroethylene and hexafluoropropylene.FEP Granule.jpg

     The melting point of FEP crystallization is 304 ℃ and the density is 2.15g / cm3. It is a soft plastic with lower tensile strength, wear resistance and creep resistance than many engineering plastics. It is chemically inert and has a low dielectric constant of 2.1g in a wide range of temperatures and frequencies. The material does not ignite and can prevent the flame from spreading. It has excellent weathering resistance and low friction coefficient. It can be used from low temperature to 392F.

     The material can be made into granular products for extrusion and moulding, powder for fluidized bed and electrostatic coating, or water dispersions. Semi-finished products have film, plate. Rods and single fibers.FEP Granule for wire and cable insulation.jpg

     FEP, a U.S. market distributor, has DUIPontundefineds Teflon and Daikin undefineds Neoflo and Hoechst Celanese undefineds IHoustaflow. Its main purpose is to make inner linings of pipes and chemical equipment, the surface of rollers and all kinds of wires and cables, such as aircraft hooks, booster cables, alarm cables, Flat cable and well logging cable. FEP film has been used as thin coating for solar collector. FEP or F46 is a copolymer of tetrafluoroethylene and hexafluoropropylene, and the content of hexafluoropropylene is about 15%.

 

     The F-46 resin has not only the same properties as polytetrafluoroethylene propylene, but also the good processability of thermoplastic. As a result, it makes up for the difficult processing of PTFE and makes it a substitute for PTFE. It is widely used in the production of electric wires and cables for transmission wires, which are used in electronic equipment at high temperature and high frequency. Internal connections for computers, aerospace wires and special purpose mounting wires, oil pump cables and submersible motor winding wires. According to processing needs, F-46 can be divided into granular, dispersive and lacquer. According to its melting index, pellets can be used for moulding, extrusion and injection molding; dispersions for impregnation and sintering; lacquer for spraying, etc.
