Ammonium Polyphosphate(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 phosphateester. Following dehydration of the phosphateester, a carbon foam is built up on the surface and acts as an insulation layer.
Use :
In plastics(PP, PVC, PE, etc. ), Polyester, Rubber, and Expandable fireproof coatings.
