Ammonium Polyphosphate
Application:
It can be used in expanding fireproof material, such as polyurethane, UP resin and epoxy resin.
Also used in the retardant of fibre, wood and plastic. APP is main ingredient of expanding
retardant thermoplastic because of its high molecular weight and good heat stabilization.
Especially used in the PP achieving UL94-V0 for electronic unit.
