APP-0S is a product based on ammonium polyphosphate. The crystal modification is phase II. It is manufactured from APP-1 by micro-encapsulation with Silicon according to Xingxing own method. APP-0S 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-0S differs from APP-1 in the following properties:
– marked reduction in water
– -soluble constituents
– even lower viscosity in aqueous suspension
Main use in Plastic(PP,PE,PA,PVC,PBT),PU, Rubber, Paint, coating
