Triphenyl Phosphate (TPP)

Triphenyl phosphate, abbreviated as TPP, exhibits excellent flame retardancy and plasticizing properties in the processing of engineering plastics such as polyurethane, phenolic resin, and PPO, effectively improving the flowability and plasticity of plastics. TPP boasts high purity, low acidity, and low color. Its insulation, compatibility, water resistance, antibacterial properties, and oil resistance significantly outperform similar flame retardants and plasticizers.

IV. Applications and Usage

Triphenyl phosphate (TPP) can be used as a flame retardant plasticizer for engineering plastics such as nitrocellulose, triacetin thin esters and films, rigid polyurethane foam, phenolic resins, and PPO. It can also be used to increase the plasticity and flowability of plastics during molding and processing. It can also be used as a plasticizer for plastics such as nitrocellulose, cellulose acetate, and polyvinyl chloride. It can also be used as a stationary phase for gas chromatography, a plasticizer for cellulose and plastics, and a non-flammable substitute for camphor in celluloid.
