Product Description

Ammonium Polyphosphate (APP)Fertilizer Grade

Ammonium Polyphosphate(APP)

Ammonium Polyphosphate 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.

Product Advantage

 

(1)High degree of polymerization up to 1300, excellent performance of fire protection in intumescent systems, has more wide range of application than low polymerization APP.
(2)Initial decomposition temperature 280 degree Celsius, action time earlier than other common ammonium polyphosphate
(3)Low water solubility, high polymerizaiton and intial decompostion temperature make our ammonium polyphosphate good compatibility.
 

 

Product Application

Ammonium Polyphosate can be used in top-grade fire-retardant coating, fiberglass and engineering plastic, such as PE, PP, PU, polyester and nylon.
(1) With 15-20% APP in the adhesive and sealing agent, the good firing resistance is shown.
(2) For PU, APP is a very suitable preventing form buring dope without halogen.
(3) It is also applicated in hot solidifying resin of epoxy resin or unsaturated resin, etc.
 

 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.

Packaging & Shipping
