APP is non-tocxic fire retardant, but you should wear defence for it is very tiny powder
 
Uses: APP are used in expanding fire-refractory coating and PU foamalso applied in fiber, wood and plastic rubber. It has high molecular weight (n>1000) and high stability, it can be used in expanding fire-refractory coating
 
Packing:25kg in PE lined woven bag

1.Advantage OF Our Ammonium Polyphosphate

(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.

2. Main 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.
