Ammonium polyphosphate(phase-II)
(CF-APP201)
Molecular formula : (NH4PO3)n n>1000
CAS No.: 68333-79-9
EINECS No.: 269-789-9
Model No.: CF-APP201
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 phosphate ester. Following dehydration of the phosphate ester, a carbon foam is built up on the surface and acts as an insulation layer.
