APP / Ammonium Polyphosphate / Flame retardant

Molecular Formula: (NH4PO3)n

Properties:

1. Much low solubility in water, with high polymerization degree;

2. High content of phosphorus and nitrogen, good flameproof effect;

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.
