Ammonium polyphosphate (Phase II) is a non-halogen flame retardant.
It acts as a flame retardant by the 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 phosphate ester. Following
dehydration of the phosphate ester, a carbon foam is built upon the
surface and acts as an insulation layer.
