Melamine formaldehyde resin coated Ammonium polyphosphate

Molecular formula: (NH 4 PO 3 ) n n>1000
CAS No.: 68333-79-9
EINECS No.: 269-789-9
Product description: Melamine formaldehyde resin coated Ammonium polyphosphate is a flame retardant based on ammonium polyphosphate. It is manufactured from ammonium polyphosphate by micro-encapsulation with melamine resin according to Changfeng’s own method. Melamine formaldehyde resin coated Ammonium polyphosphate is a fine-particle white powder with very low solubility in water, even at elevated temperatures. It is completely insoluble in organic solvents. The product is non-hygroscopic and non-flammable.

Solubility in Water(g/100ml,60℃,24h)                                ≤0.4

It can be used for all applications where the ammonium polyphosphate is required to have extremely low water solubility even
in 60℃hot water and where lower heat stability at temperatures above 300 °C contributes to more rapid foaming of the coating.
