PRODUCT DESCRIPTION
Ammonium polyphosphate is a kind of high quality, highly effective, non-toxic tasteless, does not produce corrosion gas, moisture absorption of small, high thermal stability, good performance of non halogen flame retardant. Is all sorts of expansion type fire retardant coating and fire retardant products will add fire retardant additives. We adopt international advanced technology of multilayer microcapsules coated, big, high nitrogen content, phosphorus content has good thermal stability, solubility in water is small, nearly neutral, flame retardant, high efficiency, etc. Product is the solid white powder form, no moisture absorption, nonflammable, crystallization and has high molecular weight (n > 1000) and high stability, so it can be used as expansion type flame retardant thermoplastic's main effective components.
