CAS No.: 68333-79-9 APP Intumescent Flame Retardant For Fire Protection Coating
Taifeng Company, established in October 2001, is a national high-tech enterprise integrating production, research and development, and sales of environmentally friendly flame retardants. The factory covers an area of 24 acres. It has built an automated production line with stable quality and an annual production capacity of more than 10,000 tons, which can meet customer purchase needs at any time.
Flame retardant mechanism of Phosphorus series flame retardant
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.
