Melamin resin coated ammonium polyphosphate is made by the melit surface modification.
1. Reduce the solubility in water 2. Significantly decrease the viscosity in water. 3. Obvious improvement of the dispersity and compatibility with flame retardant basic material. 4. Increase the liquidity of the powder. 5. Improve the anti-precipitation ability in flame retardant material.
Appearance: White liquidity powder P content: (%, W/W) ≥28 N content: (%, W/W) ≥17.5 pH: (25οC, 10% suspension) 7.5-8.5 Moisture content: (%, W/W) ≤0.2 Thermal decomposition temperature: ≥285οC Solubility: (25οC, g/100ml H2O) ≤0.15 Average particle size: About 10μm Bulk density: (g/cm3) 0.7 Viscosity: (25οC,10% suspension) MPa·S≤20
Packing: Kraft paper sacks lined with plastic bag, woven bags lined with plastic bag. Net weight 25kg. has very good application effect on thermoplastic and thermoset engineering materials. The halogen free flame retardant requirement can be easily achieved by using melamine coated ammonium polyphosphate as the flame retardant major active ingredient of basic material.
