2. USES
Crystalline phase II ammonium polyphosphate is a kind of environment protection nonhalogen flame-retardant cotaining N and P. It has high polymerization degree good heat-stability and small hydroscopicity. It deiffers from the halogen flame-retardant, the expansion carbon film formed during burning shows the flame-retardancy due to insulating heat and air There is low smoke, low toxic and non melting drop. So it is a kind of high efficiency environment protection inorganic flame-retardant.
Crystalling phase II ammonium polyphosphate has a wide range of use. It is suitable for plastic (PP, PE, PVC etc.), polyester, rubber, various advanced expansion fire-retardant paint.
