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.
