14728-39-3 ammonium polyphosphate APP
Crystalline type II ammonium polyphosphate is a halogen-free environmentally friendly flame retardant with a nitrogen-containing structure. The product has a high degree of polymerization, good thermal stability, and low hygroscopicity. It is different from halogen-containing flame retardant. During the combustion process, the expanded carbon layer of the product achieves the flame retardant effect of heat insulation and air isolation, and has low smoke, low toxicity, and no melt dripping. It is an efficient inorganic environmentally friendly flame retardant material.
