Description

Ammonium Polyphosphate(APP)

Ammonium Polyphosphate APP-II CAS No.68333-79-9
Product Description
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.

 Usage  

Mainy use for Expansion type fireproof paint and Polyurethane rigid foam, It can also be used for fiber, wood and rubber and plastic products of the flame retardant. Because the product is high molecular weight (n > 200) and high stability, it also can be used as expansion type flame retardant thermal plastic the main effective components, especially used in the manufacture of electronic components to UL94 - V0 in polypropylene.
