Product Description Ammonium Polyphosphate(APP) with CAS 68333-79-9 (NH4PO3) Product DescriptionIt can be used in expanding fireproof material, such as polyurethane, UP resin and epoxy resin. It can also be used in the retardant of fiber, wood and plastic materials. 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.
