Product Description

White Powder Ammonium Polyphosphate Flame Retardant For Steel Fire Protection


Product description:


Ammonium Polyphosphate (Phase II is a halogen-free flame retardant that acts as a flame retardant by an expansion mechanism. When APP II is exposed to fire or heat, it decomposes into polymeric phosphoric acid and ammonia. Polyphosphoric acid and ammonia The hydroxyl group reacts to form an unstable phosphate. After the phosphate is dehydrated, a carbon foam is formed on the surface and acts as a thermal insulation layer.
