Description
An aromatic phosphate that was commonly used as a Flame retardant and Plasticizer. Triphenyl phosphate (TPhP) was placed on the EPA Toxic Substance list in 2014 as a compound that exhibits acute and chronic aquatic toxicity. As a flame retardant, TPhP decomposes with heat to form Phosphoric acid, then further reacts to form pyrophosphoric acid which acts as a heat transfer blocker. In industry, TPhP is considered to be one of the most effective flame retardant for certain polymers, such as polyvinylchloride.
Synonyms and Related Terms
TPhP; TPP
