Product Description

       CAS NO. 68333-79-9 Ammonium Polyphosphate Flame Retardant For Fireproof Coating

 

Ammonium polyphosphate is a long chain polymer without branches. The general formula of molecular structure is (NH4) N +2PnO3n+1. When n is large enough, it can be written as (NH4) N +2PO3n+

 

How does ammonium polyphosphate work?

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.
