Ammonium polyphosphate is a non-halogen flame retardant. It acts as flame retardant by intumescence mechanism. When APP is exposed to fire or heat, ammonium phosphate 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.
