Product Usage-BPS

  • 4,4'-dihydroxydiphenyl hydrazine is mainly used as a fixing agent.
  • Reacted from phenol and sulfuric acid.In addition, it can be used as a plating bath additive, a leather tanning agent, a dispersing agent for high-temperature dyeing of disperse dyes, a phenolic resin hardening accelerator, a resin flame retardant, and the like.
  • As a substitute for bisphenol A, it can be used as a raw material for polycarbonate, epoxy resin, polyester, phenolic resin, and as a raw material for polyfluorene or polyether oxime.
  • The product is also used in the manufacture of color photographic materials, contrast enhancers, thermosensitive recording materials (developers), daily surfactants, and high-efficiency deodorants.
  • Fixing agent A (foreign trade name Cibatex PA) can be obtained by using bisphenol S as a raw material.
  • It has excellent heat resistance, light resistance and oxidation resistance, and is a raw material for synthesizing polycarbonate, epoxy resin and polyfluorene and polyether oxime resin.
  • It can also synthesize dye fixing agent and leather tanning agent with bisphenol S, and can also be used as intermediates for electric additives, dyes, medicines, pesticides and additives.
