Tricresyl Phosphate

Tricresyl Phosphate (CAS 1330-78-5) is a Technical Grade organophosphate ester supplied as a colorless to light yellow or brown liquid, valued for low volatility and compatibility with synthetic resins, and used as a flame-retardant plasticizer and extreme pressure lubricant additive. It is a clear, viscous liquid that significantly enhances the fire resistance and thermal stability of various polymer systems. It acts as a critical extreme pressure (EP) additive, improving the load-bearing capacity of industrial lubricants and hydraulic fluids. Commercially, it serves as a robust functional additive in the production of Flame Retardant PVC and nitrocellulose coatings. Its ability to reduce smoke density and prevent combustion makes it indispensable in high-safety industrial environments.
