Safety toxicity: APP is a non-toxic flame retardant, but because it is a very fine powder, attention should be paid to this aspect of protective measures during processing.
Application: APP is mainly used in intumescent fireproof coatings and polyurethane foam, and can also be used for flame retardant of fiber, wood and rubber and plastic products. Due to its high molecular weight (n > 1000) and high stability, the product can also be used as a major active ingredient in expansive flame retardant thermoplastics, especially in polypropylene up to UL94-V0 used in the manufacture of electronic components
Packaging: Lined with polyethylene bag, outsource compound paper bag, net content of 25kg.
