hexafluoropropylene

the monomers vinylidene fluoride (CH₂=CF₂), hexafluoropropylene (CF₂=CFCF₃), and chlorotrifluoroethylene (CF₂=CFCl) in addition to tetrafluoroethylene. These elastomers have outstanding resistance to oxygen, ozone, heat, and swelling by oils, chlorinated solvents, and fuels. With service temperatures up to 250° C (480° F), they are the elastomers of choice for use in industrial…
