Tpp is white odorless tablet or powder crystal, nonflammable, slightly deliquescent; Melting point 50-51C, boiling point 245C. Insoluble in water, soluble in ethanol, soluble in benzene, chloroform, ethylene, acetone and other organic solvents, but also soluble in vegetable oil; It has low volatility, transparency, softness, toughness, plasticized flame retardancy and excellent light stability.
1. It is used as nitrocellulose and cellulose acetate, flame retardant plasticizer, fire-resistant solvent, nitrocellulose paint, synthetic resin, sizing agent for roof paper, and camphor substitute in celluloid manufacturing.
2. Flame retardant plasticizer. It is mainly used as flame retardant plasticizer for engineering plastics and phenolic resin laminate, as well as flame retardant plasticizer for nitrocellulose and acetate fiber (sheet base) and plasticizer for PVC. It is also used as softener of synthetic rubber, gasoline resistant agent, incombustible substitute of camphor in viscose fiber, raw material for manufacturing trimethyl phosphate, etc.
