Sell ammonium polyphosphate phase II

Description

Ammonium polyphosphate (phase-II) Molecular formula : (NH4PO3)n n>***0 CAS No.: *********9 EINECS No.: ********9 HS CODE: ***5.***0 Model No.: TF-APP**1, TF-APP**2 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.
