APP is the halogen-free and environment-friendly flame retardant with P-N mesh structure.It has high degree polymerization,good thermal stability,and weak hygroscopic.It is different from the halogen-containing flame retardants. In the combustion process, the swelling carbon layers take the function of flame-retardant by insulating and isolating the air.It is a high efficient environment-friendly inorganic flame-retardant material with smoke-free,non-toxic,non-metal.
