Crystal :Phase II APP-1 is a fine-particle ammonium polyphosphate produced by a special method. The product is largely insoluble in water and completely insoluble in organic solvents. It is colourless, non-hygroscopic and non-flammable. APP-1differs from most other commercial products in the following ways: - greatly reduced solubility in water - lower viscosity in aqueous suspensions - lower viscosity in PU polyol suspensions - very low acid number Main use in Plastic(PP,PE,PA,PVC,PBT),PU, Rubber ,Paint ,coating
