Molecular formula : (NH4PO3)n n>1000 CAS No.: 68333-79-9 EINECS No.: 269-789-9 HS CODE: 2835.3990 Model No.: TF-FR201, TF-FR201S
產品簡介
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.
