Flame retardant is a flame retardant It is a type of additive that can prevent polymer materials from igniting or inhibit the spread of flames. It exerts its flame retardant effect through several mechanisms, such as endothermic effect, covering effect, chain reaction inhibition, suffocation effect of non-flammable gas, etc. Most flame retardants achieve flame retardant purposes through several mechanisms working together.
The heat released by any combustion in a short time is limited. If part of the heat released by the fire source can be absorbed in a short time, the flame temperature will decrease, radiate to the burning surface and act on the gasification process. The heat required to crack the combustible molecules into free radicals will be reduced, and the combustion reaction will be inhibited to a certain extent. Under high temperature conditions, the flame retardant undergoes a strong endothermic reaction, absorbs part of the heat released by combustion, and lowers the temperature of the surface of the combustible material, which is effective It effectively inhibits the generation of flammable gases and prevents the spread of combustion.
Today Shanghai Kaiyin Chemical will explain to youThe performance and main uses of TPP flame retardants:
TPPFlame retardant It is a white odorless tablet or powder crystal, non-flammable ;”>,Slightly deliquescent; melting point50- 51C, boiling point245C. Insoluble in water, soluble in ethanol, easily soluble in benzene, chloroform, ethylene, acetone and other organic solvents, and also soluble in vegetable oil; low volatility, with transparency, softness, toughness, plasticizing, flame retardancy and excellent optical properties. stability. Triphenyl phosphate(Flame retardant TPP) is a halogen-free environmentally friendly flame retardant containing phosphorus elements. Most of the products on the market are self-colored flake crystals. The modified product is Self-colored crystalline powder is also more suitable for dissolving in organic solvents.
Main uses:
TPPFlame retardantUsed as nitrocellulose and acetate, flame retardant plasticizer, fire-resistant solvent, nitric acid Cellulose paint, synthetic resin, sizing agent for roofing paper, and camphor substitute in celluloid manufacturing.
Flame retardant plasticizer. It is mainly used as a flame retardant plasticizer for engineering plastics and phenolic resin laminated boards. It is also used as a nitrocellulose, Fire retardant plasticizer for acetate fiber (film base) and plasticizer for polyvinyl chloride. It is also used as a softener for synthetic rubber, a gasoline-resistant agent, a non-flammable substitute for camphor in viscose fibers, and a raw material for the manufacture of trimethyl phosphate, etc.
