APP‐204 is a product based on ammonium polyphosphate. The crystal modification is phase II. It is manufactured from APP‐201 by micro‐encapsulation with Silicon according to own method. APP‐204 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. APP‐204 mainly use in Plastic(PP,PE,PA,PVC,PBT),PU, Rubber, Paint, coating.
