Product Description

Ammonium Polyphosphate(APP) as Flame Retardant

 

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.
