For the production of fluororubber:

Fluoroelastomer (FKM) is a synthetic polymer elastomer containing fluorine atoms on the carbon atoms of the main chain or side chain, which has excellent high temperature resistance, high chemical stability, weather resistance, oxidation resistance, oil resistance and very low air permeability.

Application of hexafluoropropylene

Hexafluoropropylene is copolymerized with vinylidene fluoride, tetrafluoroethylene, etc. in a certain proportion to produce fluororubber with ultra-high heat resistance, ultra-low flow resistance, corrosion resistance and solvent resistance.

The copolymerization of hexafluoropropylene and tetrafluoroethylene can obtain polyperfluoroethylene propylene (FEP). Compared with PTFE, FEP not only has the remarkable characteristics of melting processing, but also has excellent dielectric properties, electrical insulation properties, chemical solvent resistance, flame retardancy, high and low temperature resistance. It can be used for a long time at - 80 ℃~200 ℃.

FEP is widely used in wires and cables. At present, the applications with high added value include network cable, ultra-fine coaxial line, signal transmission line, electronic wire, shielded wire, foam cable, etc. The demand is still expanding.

For the production of perfluoroepoxypropane:

Perfluoroepoxy propane (HFPO) can be prepared by oxidation of hexafluoropropylene. As an important fluorine containing intermediate, HFPO is mainly used to synthesize high-grade fluorine containing functional compounds, such as perfluoropolyether, fusible polytetrafluoroethylene, perfluoroacetone, etc.

Among them, perfluoropolyether is a special lubricating material commonly used in military, aerospace and other high-end fields; In addition, as the only material that can resist the corrosion of uranium hexafluoride at 130 ℃, perfluoropolyether is widely used in the nuclear industry. The fusible polytetrafluoroethylene, or PFA, is the fluoroplastic with large demand in the semiconductor industry at present, and its price is usually about three times that of polytetrafluoroethylene.

For production of heptafluoropropane:

Heptafluoropropane, obtained from hexafluoropropylene through hydrofluorination reaction, is a clean gas fire extinguishing agent mainly used for chemical fire extinguishing and also used for physical fire extinguishing. Since its ODP value is zero, it will not pose a threat to the atmospheric ozone layer. With the prohibition of halon, the demand for heptafluoropropane is gradually increasing. Because it is colorless, odorless, non-conductive, and does not pollute the protected object, it is often used to extinguish precision facilities and electrical fires.

In addition, heptafluoropropane has a wide market as a medical aerosol.
