Bisphenol AF (BPAF) is a fluorinated organic compound that is an analogue of bisphenol A in which the two methyl groups are replaced with trifluoromethyl groups.

Instead, BPAF activates ERR-α and binds to and disables ERR-β.

[4] Bisphenol AF is used as a crosslinking agent for certain fluoroelastomers and as a monomer for polyimides, polyamides, polyesters, polycarbonate copolymers and other specialty polymers.

Polymers containing Bisphenol AF are useful in specialties such as high-temperature composites and electronic materials.

Industries include cosmetics, chemical manufacturing, production of metals and rubber.
