Product Name: Hot Selling Ammonium Polyphosphate for Flame Retardant CAS 68333-79-9 Model NO.: YX1805 Grade Standard: Industrial Grade Type: Ammonium Polyphosphate Purity: ?99% Certification: ISO EINECS: 269-789-9 Formula: H12n3o4p CAS No.: 68333-79-9 Trademark: YANXI Transport Package: 25kg /Bag Specification: 25 kg /bag Origin: China Hebei HS Code: 2824100000 Product Description PRODUCT DEscriptIonAmmonium 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.AppearanceWhite powderPhosphorus pentoxide content%(w/w)≥71nitrogen content%(w/w)≥14decomposition temperatureºC275density (25ºC)g/cm3≈1.9solubilityg/100ml H20, 25ºC≤0.5pHvalue10% serous fluid6~7.5viscosity(10% serous fluid, 25ºC)m Pa·s<60Water content%(w/w)<0.25Average particle sizeµm<20
