Hexafluoropropylene (R1216, HFP) is a colorless and odorless gas at room temperature and pressure. It is one of the most important fluorine-containing monomers. It can be copolymerized with other olefins to prepare fluorine-containing polymer materials. It is a pharmaceutical intermediate and a fire extinguishing agent.R227ea, refrigerantR1234yfand other raw materials for fluorinated fine chemical products.
