What is FEP? What is FEP?
Today, Dankai Teflon tube little sister saw many people on the Internet inquiring about "what material is FEP? Or what is FEP?" Now, Teflon tube little sister will explain to you what material FEP is:
FEP crystalline melting point of 580F, density of 2.15g/cc (grams/cubic centimeter), it is a soft plastic, its tensile strength, wear resistance, creep resistance is lower than many engineering plastics. It is chemically inert and has a low dielectric constant (2.1) over a wide range of temperatures and frequencies. The material does not ignite and can prevent the spread of flame. It has excellent weather 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.
What is the material of FEP or F46: it 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 difficulty of processing polytetrafluoroethylene and makes it a material to replace polytetrafluoroethylene. It is widely used in the production of wires and cables for electronic equipment transmission wires used at high temperature and high frequency, connecting wires inside electronic computers, aerospace wires and special purpose installation wires, oil pump cables and insulating layers of 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.
Summary FEP is also called F46 in the fluorine raw material industry. Due to processing needs, three forms have been formed: pellets, dispersions and paints. This is Teflon tube little sister: "FEP is what material?".
