FEP is the polymerization of tetrafluoroethylene and hexafluoropropylene. The melting point of FEP crystal is 304℃ and the density is 2. 15g/CC (g/cm3). FEP can be applied to soft plastics, and its tensile strength, wear resistance and creep resistance are lower than many engineering plastics. It is chemically inert and has a low dielectric constant in a wide temperature and frequency range.

Use of fep

Perfluoroethylene propylene resin has similar characteristics to PTFE and good processing technology of thermoplastics, and is an important material to replace PTFE. F-46 is widely used in the production of wires and cables, such as transmission lines of electronic equipment used at high temperature and high frequency, connecting wires inside electronic computers, wires used in aerospace, and other special-purpose installation lines, logging cables in oil mines, winding wires of submersible motors, lead-out wires of micromotors and so on. ?

The difference between pfa and fep

1, the most basic distinction: pfa is resistant to 260 degrees and fep is resistant to 200 degrees.

2. Processing temperature: pfa is about 385 degrees, fep is about 350 degrees.

3. Specific gravity: pfa has a slightly larger specific gravity.

4.pfa continues to perform slightly better.
