Uses: APP is mainly used in intumescent fire retardant coatings and polyurethane foam, also be used in the flame retardance of fiber, wood and rubber products. With high Molecular Weight (n>1000)and stability, it can be used as the active matter of intumescent flame-retardant thermoplastic, especially for fire retardant PP (UL94-V0) and cable materialsPacking: PE bag lined composite paper bag, Net wt 25kg.
