1. FEP liquid delivery pipe
FEP Liquid Delivery Pipes are suitable for fluids, corrosive liquids and gases.
FEP full name is Fluorinated ethylene propylene, translated as fluorinated ethylene propylene copolymer (perfluorinated ethylene propylene copolymer) English trade name: Teflon * FEP, is a class of chemical substances. FEP is a copolymer of tetrafluoroethylene and hexafluoropropylene. The FEP crystals had a melting point of 304 ° C. and a density of 2.15g/cc.
FEP can be applied to soft plastics, the tensile strength, wear resistance, creep resistance is lower than many engineering plastics. It is chemically inert and has a low dielectric constant over a wide range of temperatures and frequencies.
The material does not ignite and can prevent the spread of flame. It has excellent wear resistance and low friction coefficient, which can be used from low temperature to 392F. The material can be made into granular products for extrusion and molding, as powders for fluidized beds and electrostatic finishes, and also into aqueous dispersions. Semi-finished products have film, plate. Rods and single fibers. FEP distributed in the U.S. market is Teflon from DUIPont, Neoflo from Daikin, and IHoustaflow from Hoechst Celanese. Its main use is for the production of pipe and chemical equipment lining, drum surface and a variety of wires and cables, such as aircraft hook line, pressurized cable, alarm cable, flat cable and oil well logging cable. FEP films have been used as thin coatings for solar collectors.

FEP or F46 is a copolymer of tetrafluoroethylene and hexafluoropropylene. The content of hexafluoropropylene is about 15%, and it is a modified material of polytetrafluoroethylene.
F-46 resin has both the characteristics similar to polytetrafluoroethylene and the good processability of thermoplastics. Therefore, it makes up for the lack of processing difficulties of PTFE, making it a material to replace PTFE. In the production of wire and cable, it is widely used in electronic equipment transmission wires used at high temperature and high frequency, electronic computer internal connection wires, aerospace wires and special purpose installation wires, oil pump cables and submersible motor winding wires.
According to processing needs, F-46 can be divided into three kinds of pellets, dispersion and paint. Among them, according to the different melt index, the pellets can be used for molding, extrusion and injection molding; the dispersion liquid is used for impregnation and sintering; the paint is used for spraying, etc.
