Product Name:Melamin resin coated ammonium polyphosphate

Brief introduction:

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.

Property index:

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

1. Intumescent flame retardant coating
2. Architechtural flame retardant board, coil and halogen free flame retardant shell
3. Cable, rubber and polyolefin products.
4. Polyester, polyurethane, epoxy resin and UPR
5. Fibre products
Product Name:  Melamin resin coated ammonium polyphosphate

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.
