Documented Uses

  • Used as flame retardant plasticizer for polyvinyl chloride, cellulosics, and other vinyl polymers; [HSDB]
  • tert-Butylphenyl diphenyl phosphate is a slightly less efficient plasticizer for PVC by itself (... compared to other aryl phosphates), but it is quite effective in blends with, eg, phthalates. It has been used as a flame retardant in engineering thermoplastics and as a fire-retardant hydraulic fluid.
  • Processing aids not otherwise specified
  • Not Known or Reasonably Ascertainable
  • PROBABLY BY REACTION OF PHOSPHORUS OXYCHLORIDE WITH T-BUTYLPHENOL & PHENOL IN THE PRESENCE OF A CATALYST
