The Detailed Introduction Of FEP
- Oct 01, 2018 -

     The content of hexafluoropropylene (HCP) is about 15%, and it is a modified material of polytetrafluoroethylene (PTFE), which is composed of tetrafluoroethylene (TFE) and hexafluoropropylene (HCP).

      Full name: ethylene fluoride propylene copolymer (perfluoroethylene propylene copolymer), referred to as polyfluoroethylene propylene, also abbreviated as F 46. The melting point of FEP crystallization is 580 °F and the density is 2.15g/CC (g / m3 cm).

      It is a kind of soft plastics.

      Its tensile strength, wear resistance and creep resistance are lower than those of many engineering plastics.

      It is chemically inert and has a low dielectric constant of about 2.1 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, which can be used from low temperature to 392 °F. 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, a U.S. market distributor, has DUIPontundefineds Teflon and Daikinundefineds Neoflo and Hoechst Celaneseundefineds IHoustaflow. Its main purpose is to make inner villages for 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.


     F 46 resin not only has similar properties to PTFE, but also has good processability of thermoplastic. As a result, it makes up for the difficult processing of PTFE and makes it a substitute for PTFE. It has been widely used in the production of wire and cable for transmission wires and connections within computers for electronic equipment used at high temperature and high frequency. Insulation layer for aerospace wires and their 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.
