Product information:Ammonium polyphosphate (APP-II)Synoyms: White powder Chemical Formula: Hn+2PnO3n+1Cas No:68333-79-9Product description:TY-423 is a long-chain crystal phase II ammonium polyphosphate(n≥1000). It has a higher thermal stability and lower water solubility than crystal phase II Ammonium Polyphosphate.TY-423 is an environmentally friendly halogen free flame retardant, which develops its effectiveness through phosphorus / nitrogen synergism and also can be compatible with other polymers. It is usually used with charring agent and foaming agent to protect the polymer through its heat-insulating effect.Applications:-Used in making intumescent fire-retardant coatings for buildings, vessels, trains, cables, ect.- Used in flame retardant on wood, veneer, paper, fiberboard.-Use as the main additive of IFR for plastic, resin, rubber.-Used in making dry poweder extinguisher for forest, coalfield and oil field fire.TY-423 Specifications:ItemUnitIndexDegree of polymerization (n)≥1000 (NMR)P2O5 Content%(w/w)≥71Nitrogen(N) Content%(w/w)≥14pH Value (10% suspension)5.5—7.5Water Content (130℃)%(w/w)≤0.5Solubility in water (25℃)g/100Ml≤0.5Viscosity (25°C, 10% suspension)mPaS≤100Density (25℃)g/cm3about 1.9Bulk Density (25℃)g/cm3about 0.7Thermal Decomposition Temp.
