quantity: 2000 specs:flame retardant price:3.5 usd kilograms payment method: tt or lc ammonium polyphosphate (xap-03) appearance : white powder cas no.68333-79-9 specifications: p (%) : 22±1 density (g/cm3): approx. 1.8 bulk density (g/cm³ ): approx. 0.45 decomposition temperature 250℃ min solubility in water (25℃ g/100mlh2o) 0.5g max ph 5.0~7.5 average particle size : 16um max xap-03 is a non-halogenated flame retardant based on app-1 which develops its effectiveness through phosphorus / nitrogen synergism. when incorporated into thermoplastics, it exhibits high processing stability. xap-03differs in its mode of action from chlorine- or bromine-containing flame retardants by achieving its effect through intumescence. the thermoplastic material foams on exposure to flame. the carbon foam layer so formed protects the polymer through its heat-insulating effect, reduces fur-ther oxygen access and prevents dripping of the thermoplastic. applications: xap-03 may be used in poly-propylene, pp-copolymers and pp-blends. the application areas are nearly the same as for xap-02. compared to xap-02, xap-03 shows an improved thermal stability, which allows an approx. 30°c larger processing win. in compounding of xap-03, a reduced water uptake, less contamination of the water bath and less soapiness of the polymer strength is observed. xap-03 is a suitable non-halogenated flame retardant for polyurethane foams. if handling of xap-03 as a solid is not possible we recommend the dosage of the flame retardant by preparing an xap-03/polyol-suspension. because of the low acid number ofxap-03 it is also possible to incorporate this flame retardant in anxap-03/isocyanate suspension. to prevent the solid from settling the xap-03 suspensions should be stirred or circulated by pump. |
