4,4'- dihydroxydiphenyl sulfone is mainly used as fixing agent. In addition, it can be used as bath additive, leather tanning agent, dispersant for high-temperature dyeing with disperse dyes, phenolic resin hardening accelerator, resin flame retardant, etc. It is also the intermediate of pesticides, dyes and additives,Raw material Of Thermal Sensitive Material,. As a substitute of bisphenol A, it can be used as the raw material of polycarbonate, Polymer Materials of Bisphenol S,epoxy resin, polyester and phenolic resin, as well as polysulfone and polyether sulfone. This product is also used to manufacture color photographic materials, photographic contrast enhancers, thermosensitive recording materials (color developers), daily surfactants and high-efficiency deodorants. Fixing agent A (Cibatex PA) can be prepared from bisphenol S as raw material. As a monomer for synthesizing polysulfone resin, it can also be directly used in coatings, Surfactant For Daily Use,leather modifiers, dye intermediates, metal plating brighteners, etc.
