Application

Triphenyl phosphate has been used widely as a flame retardant and plasticizer.It has been used as a flame retardant for a variety of materials, including electronic equipment, PVC, hydraulic fluids, glues, and casting resins. 

Its mechanism of action as a flame retardant is as follows: first, during thermal decomposition, phosphoric acid is formed. This reacts to form pyrophosphoric acid, which, when in its condensed phase, acts to block heat transfer. One of the most effective flame retardants for certain polymers, TPP is only active as an additive flame retardant in its gas phase.Phase out of PBDEs may have increased the use of TPP in recent years.

TPhP is also used as a plasticizer in lacquers, varnishes, and hydraulic fluids. Nail polish has received particular interest as a source of exposure to TPhP.
