Product description:
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 reacts with hydroxyl groups to form a nonstable phosphateester. Following dehydration of the phosphate ester, a carbon foam is built up on the surface and acts as an insulation layer.
Advantage :good stablility in water
The stability test of App phase II in 30℃ water 15days
