Ammonium polyphosphate (Phase II) is a non-halogen flame retardant. It acts as flame retardant by intumescence

mechanism. When APP-II is exposed to fire or heat, it decomposes to polymeric phosphate acid and ammonia. The

polyphosphoric acid reacts with hydroxyl groups to form a nonstable phosphateester. Following dehydration of the

phosphateester, a carbon foam is built up on the surface and acts as an insulation layer.

Specification :

Advantage: It has good stability in water .
                                                                  The stability test of APP phase II in 30ºC water 15days

Applications:

1. used to prepare many kinds of high-efficiency intumescent coating, the flameproof treatment for wood, multistory building,

ships, trains, cables, etc.

2. used as the main flameproof additive for expanding-type flame retardant used in plastic, resin, rubber, etc.

3. make into powder extinguishing agent to be used in large-area outfire for forest, oil field and coal field, etc.

4. In plastics(PP, PE, etc. ), Polyester, Rubber, and Expandable fireproof coatings.

5. used for textile coatings.
