2. Introduction
Its content as high as 30&percnt;~32&percnt; of nitrogen is 14&percnt;~16&percnt; of the most prominent feature of this kind of flame retardant is the amount of smoke when burning low does not produce hydrogen halide alternative because of good thermal stability of ammonium polyphosphate ammonium phosphate&period;Ammonium polyphosphate for fine white crystalline or amorphous powder APP solubility in water and moisture absorption decreased with increasing polymer according to the different polymerization degree n can be divided into domestic water-soluble &lpar;n&equals;10~20 relative molecular mass of 1000~2000&rpar; and water insoluble &lpar;n>20 molecular weight greater than 2000&rpar; two kinds of n can be greater than 1000 abroad put n < 100 known as the crystalline phaseIammonium polyphosphate &lpar;APP&rpar; put n>1000 APP with branched chain known as crystalline phase ammonium polyphosphate &lpar;APP&rpar; n<100 short chain APP for water sensitivity &lpar;hydrolysis&rpar; is larger than long chain &lpar;M>1000&rpar; APP and higher thermal stability and resistance to hydrolysis of the long chain APP at above 300ºC began to break down into phosphoric acid and ammonia and short chain APP at above 150 ºC began to break down&period;

3&period; Application
1&rpar;&period;used to prepare many kinds of high-efficiency intumescent coating&comma;the flameproof treatment for multistory building&comma;ships&comma;trains&comma;cables&comma;etc&period;
2&rpar;&period;used as the main flameproof additive for expanding type flame retardant used in plastic&comma;resin&comma;rubber&period;
3&rpar;&period;make into powder extinguishing agent to be used in large-area outfire for forest&comma;oil field and coal field&period;
4&rpar;&period;In plastics&lpar;PP&comma;PVC&comma;PE&comma; etc&period;&rpar;&comma;Polyester&comma;Rubber&comma;and Expandable fireproof coatings&period;
APP is mainly used in intumescent coating and rigid polyurethane foam&comma;it is also used in fiber&comma; woods and rubber &plastic products as flame retardant&period; Since this kind of APP has a high molecule weight&lpar;n>1000&rpar; and its stability&comma; it is often used in intumescent flame retardant thermoplastic plastics&comma;especially used in Polypropylene to make electronic parts which can reach to UL94-V0&period;
