China Professional Ammonium Polyphosphate (APP) as Flame Retardant in Coatings

Product Description

DovaFR AP 310 _II 

Ammonium polyphosphate(APP)

DovaFR AP 310_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 phosphate ester. Following dehydration of the phosphate ester, a carbon foam is built up on the surface and acts as an insulation layer.

Benefits

1. Due to high degree of polymerization(n>1000), DovaFR AP 310_II is stable in water.

2. DovaFR AP 310_II is equivalent to AP 422 and FR Cros 484, excellent synergistic effect as flame retardant.

3. DovaFR AP 310_II is ecofriendly as a non-halogen flame retardant can be used widely in many areas.
