APS 3

Pure ammonium peroxydisulfate and silicic acid. It acts as an initiator (source of free radicals) for the emulsion or solution polymerization of acrylic monomers, vinyl acetate, vinyl chloride and emulsion co-polymerization of styrene, acrylonitrile, butadiene etc. Also acts as a strong oxidizing agent in many applications, de-sizing agent/bleach activator in textile for cold bleaching and as a disinfectant. It enhances the free flowing properties. It is a white, crystalline, odorless salt with molar mass 228,20 g/mol. It has an advantage of having a good storage stability as a result of its extremely high purity and of being easy and safe to handle. Due to its hygroscopic character it tends to lumping, especially in humid atmosphere and can be optionally supplied with an addition of silicic acid.
