  2. sell 4,4'-Sulfonyldiphenol; 4,4'-Dihydroxydiphenylsulfone; Bisphenol S

    4,4 '- dihydroxy diphenyl sulfone was mainly used for fixing agent. In addition, can be used as additive in the bath, leather tanning agent, dispersion dyes in high temperature dyeing dispersing agent, hardening accelerator of phenolic resin and flame retardant resin agent and pesticides, dyes, auxiliary intermediates. As a substitute for bisphenol A, as polycarbonate, epoxy resin, polyester, phenolic resin raw materials, as well as polysulfone, polyethersulfone (PES) of raw materials. The product is also used for making color photographic materials, photographic contrast enhancer and thermosensitive recording material (chromogenic agent), daily surface active agent and efficient deodorant. With bisphenol s as raw materials can be prepared by fixing agent a (CibatexPA).
