Hexafluoropropylene oxide (HFPO) is the oxidation product of hexafluoropropylene. It is a colorless, non-combustible gas, easy to liquefy under pressure. It is an important intermediate for organic fluorine materials. It is used to prepare hexafluoroacetone, hexafluoroisopropanol, fluorinated vinyl ethers (such as PPVE, PSVE, PEVE, PMVE), fluorinated surfactants, fluorinated ether oils, perfluorosulfonic acid resins and many other fluorinated fine chemicals or polymers are widely used in chemicals and electronics, medicine, agriculture, automobiles, new energy, military, aerospace and other important fields.
