Toxicity:
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
