Polyhexafluoropropylene oxide, or poly-HFPO, is a polymer compound, a fluorinated polyether. It is insoluble in water, acids, bases, and most of organic solvents. It is non-toxic and nonflammable, and has high thermal stability. Its properties are somewhat similar to PTFE.

It is a fluoropolymer with a chemical structure consisting of long chains of [-CF(CF3)-CF2-O-] units.

Under the trade name Krytox it is used as a lubricant with military and aerospace applications.
