Ammonium Polyphosphate
APP
Product Description
It can be used in textile coating, intumenscent fireproof coatingd, 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.
