Use Butylated triphenyl phosphate ester (same as Supresta's phosflexR71B) is a highly effective flame-retardant plasticizer, which has good compatibility with PVC and other alloys such as PPO and PC/ABS. When t-butyl phosphate is considered as a conventional plasticizer, it can balance the flame retardancy and plasticizing performance of the system. Its high thermal stability allows it to be used as a flame retardant for engineering plastics and can also improve the melting properties of plastics.
