4,4'-Biphenol Usage And Synthesis
Chemical Properties Powder
Uses Intermediates of Liquid Crystals
Uses 4,4'-biphenol be used intermediate liquid crystal polymers raw materials. Synthetic polymers, due to its excellent heat resistance, it is used as polyester, urethane modified monomer, polycarbonate, polysulfone, and epoxy resin, for the manufacture of an excellent engineering plastics and composite materials. Antioxidant antioxidants for rubber and plastics. Dye intermediates or petroleum products stabilizer.
Uses Biphenol is an intermediate used in the manufacture of thermoplastics such as liquid crystalline polymers (LCP), polyesters, polycarbonates and polysulfones.
Definition: A member of the class of hydroxybiphenyls that is biphenyl with hydroxy groups at positions 4 and 4'.
Safety Profile Poison by intraperitoneal route.Moderately toxic by skin contact. Mildly toxic byingestion. Human mutation data reported. When heated todecomposition it emits acrid smoke and irritating fumes.
