Bisphenol a BPA in thermoplastic resins
The thermoplastic resin synthesized from the sodium salt of bisphenol A BPA and 4,4'-dichlorodiphenyl sulfone can maintain its original state for a long time at high temperatures, and it has good chemical corrosion resistance and electrical insulation. The thioester synthesized from bisphenol A and diphenyl disulfonyl chloride is a thermoplastic resin, which has good transparency and electrical insulation, and is suitable for use as coatings, films and fibers. The polyarylate synthesized by the condensation of bisphenol A BPA and terephthaloyl chloride (isophthaloyl chloride) is a structural material, suitable for use as mechanical parts, electrical parts, and pipe plates. Bisphenol A BPA can also be used as a raw material for the flame retardant tetrabromobisphenol A.
