Product Description
Molecular formula: (NH4PO3)n n>1000
CAS No.: 68333-79-9
EINECS No.: 269-789-9
Model No.: BL-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.
Packing: 25kg woven bag with plastic liner.
