Superiority:

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.

1. Ammonium polyphosphate decomposition temperature is 275℃.

2. Fire resistance for flame retardant coating up to 60mins,90mins and 120mins.

3. Ammonium polyphosphate is fit for water based and solvent based fire retardant paint.
