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.
