CAS NO:1478-61-1 BPAF/Bisphenol AF

Bisphenol AF features six fluorine atoms at the molecular bridging position, bringing high-energy C-F bonds, strong electron-withdrawing effect, steric hindrance and low polarizability. It boasts outstanding thermal stability, oxidation resistance, excellent corrosion resistance to strong acids, alkalis, oils and organic solvents, as well as favorable dielectric properties.

It is chemically stable at room temperature, with phenolic hydroxyl groups capable of various reactions and controllable polymerization activity. It decomposes and combusts only at 510℃ (decomposition temperature above 300℃), making it an excellent monomer for specialty polymers.

Vulcanizing agent for fluoroelastomers . cured rubber has low compression set, good oil/acid/alkali resistance, high strength, thermal aging resistance and stable sealing.

Monomer for fluorinated polymers. Synthesize fluorinated epoxy, polyimide, polyaryletherketone for electronic adhesives, anti-corrosion coatings, aerospace composites and high-temperature plastics.

New energy & electronic materials. Fuel cell membranes, battery binders; 5G low-dielectric coatings, semiconductor insulation, optoelectronic substrates.

Pharmaceutical fluorinated intermediate. Fluorinated building block for targeted fluorinated APIs.
