 Organic Fluorides<<Bisphenol AF (BPAF)
Bisphenol AF (BPAF)
Common names: Hexafluorobisphenol A; Bisphenol AF 4,4'-(hexafluoroisopropylidene)diphenol; 2,2- bis (4 hidroxyphenyl)hexafluoropropane
Appearance:white to light-gray coarse powder.
Applications: Bisphenol AF is used to cure or cross-link fluorocarbon elastomers, often in conjunction with an accelerator such as triphenyl benzylphosphonium chloride (BTPPC). When used as a curing agent, Bisphenol AF produces fluoroelastomers with convenient processing and excellent properties in the final elastomer, including compression set, chemical resistance and thermal stability. Bisphenol AF is also useful as a monomer in the synthesis of specialty polyimides, polyamides, polyesters, polycarbonates and other polymers. Polymers containing Bisphenol AF are useful in high-temperature composites, in electronic materials, in gas permeable membranes, and in other specialty polymer applications.
