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-1different 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
