• Product description :

  Molecular formula:(NH4PO3)n n﹥1000 CAS NO:68333-79-9 Property: It 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.

• Uses :

  Widely used in plastics (PP, PE, PVC, etc.),polyester, rubber, and various high-grade expansion fire-refractory coating.
