CAS Number: 1330-78-5

Tricresyl phosphate (TCP) flame retardant grade is an aryl phosphate ester plasticizer and flame retardant for PVC, rubber, and vinyl compounds where simultaneous plasticization and fire retardancy are required. Its aromatic structure imparts superior thermal stability and low volatility compared to aliphatic phosphate plasticizers, making it suitable for high-temperature processing applications. TCP acts in both gas-phase and condensed-phase modes, reducing heat release and forming a stable char layer on combustion.
