Ammonium Polyphosphate
APP
CAS: 68333-79-9
Molecular Formula: (NH4PO3)n
Application：It can be used in textile coating, 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.
