2.Application

Water-soluble ammonium polyphosphate can be formulated into 20% flame retardant solution, which can be used for flame retardant treatment of textiles, paper, fiber and wood alone or in combination.
High molecular weight ammonium polyphosphate can ensure low water solubility, better dispersion and excellent water resistance, mainly used in intumescent fireproof coatings and polyurethane hard foam, also can be used in the flame retardant of fiber, wood and rubber products, high polymerization degree to ensure good adhesion and carbon layer stability on the coated surface after intumescent flame retardant coatings, to prevent the coating from falling off and ensure the stable performance of flame retardant effect.
