Molecular Formula: (NH₄PO₃)₂

Standard executed: HG/T2770-1996

Properties: It is an excellent, high-efficiency and nontoxic inorganic flame retardant, used as the necessary flameproof additive for all kinds of expanding-type flameproof coating and flameproof products. The degree of polymerization of our high-polymerization long-chain ammonium polyphosphate is higher than 50; the solubility in water is lower than 2g in every 100ml water.
