Specification:

1.Molecular formula : (NH4PO3)n n>1000
CAS No.: 68333-79-9
Model No.: CF-APP201
Characteristics:Ammonium polyphosphate 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.
