Ammonium Persulfate is a strong oxidizing agent with many applications, including bleaching, etching, and polymer synthesis. Ammonium Persulfate is used in the treatment of metal surfaces for the manufacturing of semiconductors, cleaning and etching of printed circuits, activation of copper and aluminum surfaces. Ammonium Persulfate is also used as a bleach activator - especially for cold bleaching in the textile industry and in hair bleaching formulations. Ammonium Persulfate is an initiator for the emulsion or solution polymerization of acrylic monomers, vinyl acetate, vinyl chloride etc. and for the emulsion co-polymerization of styrene, acrylonitrile, butadiene. Other applications include chemical synthesis, disinfection, water treatment, waste gas treatment, paper (modification of starch, re-pulping particularly for cold bleaching).
