It can be used in intumescent fireproof coatings and thermoset resins, such as polyurethane, UP resin and epoxy resin. It can also be used in the retardant of fiber, wood ,rubber and plastic products. Due to its high molecular weight(n>1000) and good heat stability, APP can be used as main ingredient of expanding retardant thermoplastic.,especially used in the PP achieving UL94-V0 for electronic unit.

CAS Number: 68333-79-9 Whiteness:90 Min. Uses: Ammonium Polyphosphate II is used as flame retardant insolvent based and water based intumescent coatings. APP II is also used as flame retardant in unsaturated polyesters, epoxies, polyurethanes and flexible and rigid urethane foams.
