Bisphenol A diphenyl phosphate is a halogen-free flame retardant used plastics. It is used in polymer blends of engineering plastics, such as PPO/HIPS and PC/ABS,[1] which are commonly used to make casing for electrical items like TVs, computers and home appliances.

It is formed by the transesterification of bisphenol A with triphenyl phosphate. The commercial grade material can contain oligomers (CAS: 181028–79–5)

Oligomers, where n = >1
Oligomers, where n = >1
