Ammonium Polyphosphate Used For Fiber, Wood And Plastic Materials Cas No 68333-79-9
Basic Spec
Ammonium polyphosphate is a kind of high quality, highly effective, non-toxic tasteless, does not produce corrosion gas, moisture absorption of small, high thermal stability, good performance of non halogen flame retardant. Is all sorts of expansion type fire retardant coating and fire retardant products will add fire retardant additives. We adopt international advanced technology of multilayer microcapsules coated, big, high nitrogen content, phosphorus content has good thermal stability, solubility in water is small, nearly neutral, flame retardant, high efficiency, etc. Product is the solid white powder form, no moisture absorption, nonflammable, crystallization and has high molecular weight (n > 1000) and high stability, so it can be used as expansion type flame retardant thermoplastic's main effective components.

Application
It 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.
