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.
