China Factory Supply Ammonium Polyphosphate Flame Retardant APP CAS 68333-79-9
Ammonium polyphosphate (phase II is a non-halogen fiame retardant, it acts a fiame 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 hydroxy 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.
