Hexafluoropropylene is the fluoroalkene with the formula CF 3 CF=CF 2. It is the perfluorocarbon counterpart to the hydrocarbon propylene . It is mainly used to produce copolymers with tetrafluoroethylene .
GenX is a Chemours trademark name for a synthetic, short-chain organofluorine chemical compound, the ammonium salt of hexafluoropropylene oxide dimer acid (HFPO-DA). It can also be used more informally to refer to the group of related fluorochemicals that are used to produce GenX.
Hexafluoropropylene oxide (HFPO) is an intermediate used in industrial organofluorine chemistry; specifically it is a monomer for fluoropolymers.This colourless gas is the epoxide of hexafluoropropylene, which is a fluorinated analog of propylene oxide, HFPO is produced by Chemours and 3M and as a precursor to the lubricant Krytox and related materials.
The production process involves 2 molecules of hexafluoropropylene oxide (HFPO) to produce hexafluoropropylene oxide dimer acid fluoride (FRD-903). The ammonium salt of FRD-903 is FRD-902 (ammonium (2,3,3,3-tetrafluoro-2-(heptafluoropropoxy)propanoate)), which is the specific chemical which Chemours has trademarked as part of GenX process. [5]
The copolymer Poly(vinylidene fluoride-co-hexafluoropropylene) or PVDF-HFP is used as a co-polymer in the blades of artificial turf. [17] Addition of organoclay to PVDF-HFP via melt compounding stabilizes the β piezoelectric phase. [18] Copolymers of PVDF are also used in piezoelectric and electrostrictive applications.
Fluorinated ethylene propylene (FEP) is a copolymer of hexafluoropropylene and tetrafluoroethylene.It differs from the polytetrafluoroethylene (PTFE) resins in that it is melt-processable using conventional injection molding and screw extrusion techniques. [2]

Krytox fluoroether-based grease pictured alongside a tube of Dow Corning silicone grease (green). Both are often used in laboratories, including in high-vacuum applications, due to their inertness.
