Hexafluoropropylene is a synthetic alkene with the formula C3F6. It is the perfluorocarbon counterpart to the hydrocarbon propylene.

Hexafluoropropylene is used as a chemical intermediate.[1] It is often used a copolymer[2] in fluoroplastics such as fluorinated ethylene propylene.

Hexafluoropropylene can be produced by pyrolysis of tetrafluoroethylene or chlorodifluoromethane, or produced from various chlorofluorocarbons.[3]

This gas can also be produced as an effluent from the decomposition of polytetrafluoroethylene when laser cutting it. [4]

Health Effects[]

Hexafluoropropylene can asphyxiate by the displacement of air.[2]
