CAS NO.: 68333-79-9
Ref. Standard: HG/T2770-1996
production capacity: 1000 t/a
Properties: White fine powder. It is an excellent, high-efficiency and nontoxic inorganic flame retardant, used as the necessary flameproof additive for all kinds of expanding-type flameproof coating and flameproof products. When 10≤n≤20, it’s soluble, when n>20, it’s relatively insoluble.
We can supply APP with n>50, and the solubility in water is lower than 2g/100ml water.
Technical Specifications:
Features:
1. high content of phosphorus and nitrogen, good flameproof effect;
2. high polymerization degree, low solubility in water and low hygroscopicity;
3. PH is near to neutral, good heat stability and good compatibleness;
4. very low toxicity (LD50>10g/kg), very safe during production and use;
Application:
1. used to prepare many kinds of high-efficiency expanding-type flameproof coating, the flameproof treatment for multistory building, ships, trains, cables, etc.
2. used in the flameproof treatment for woods, plywood, fiberboard, papers, fibers, etc.
3. used as the main flameproof additive for expanding-type flame retardant used in plastic,resin, rubber, etc.
4. made into powder extinguishing agent to be used in large-area outfire for forest, oil field and coal field, etc.
used to prepare many kinds of high-efficiency expanding-type flameproof coating, the flameproof treatment for multistory building, ships, trains, cables, etc.
