Phosphate Ester Flame Retardant Plasticizer
CAS Number: 78-51-3
Phosphate Ester Flame Retardant Plasticizers (e.g., TCP, TBEP, TDCPP) combine plasticization and flame retardancy in a single additive, reducing the need for separate flame retardant systems in PVC and polyurethane. They function by releasing phosphoric acid and forming a char layer that limits oxygen access during combustion. These products are widely used in flexible PVC wire insulation, flooring, and foam applications requiring fire safety.
