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.

Applications:
1. used to prepare many kinds of high-efficiency intumescent coating, the flameproof treatment for 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, PVC, PE, etc. ), Polyester, Rubber, and Expandable fireproof coatings.
