[Products Name]                   Bisphenol AF (BPAF)

[Molecular Formula]             (CF₃)₂C(C₆H₄OH)₂

[CAS No.]                                  1478-61-1

[Product Description]
Bisphenol AF is a white to light gray powder. It is mainly used as a cross linking agent in the synthesis of specialty elastomers. Many of these elastomers will exhibit good chemical and thermal properties.

Bisphenol AF is used to cross-link and cure fluoroelastomers, often along with an accelerator such as triphenyl benzyl phosphonium chloride.

When used as a curing agent it produces elastomers with excellent chemical resistance and thermal stability.

Bisphenol AF is also used as a monomer in the synthesis of specialty polymers. Polymers containing Bisphenol AF are useful in high temperature composites, in electronic materials and other specialty applications.
