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.
