APP‐203 is a product based on ammonium polyphosphate. The crystal modification is phase II. It is manufactured from APP‐201 by micro‐encapsulation with melamine resin according to own method. APP‐203 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. It is completely insoluble in organic solvents. APP 203 is used in Plastic(PP,PE,PA,PVC,PBT),PU, Rubber ,Paint and coating.
