POTASSIUM PERSULFATE is a white, finely crystalline, odorless salt consisting of technically pure potassium peroxodisulfate. It is used as an initiator (source of free radicals) for the polymerisation of monomers and as a strong oxidizing agent in many applications. It has the particular advantage of being only slightly hygroscopic and easy and safe to handle. As a result of the process used for its production it is free from contamination by ammonium ions. As a result of its extremely high purity it has a good storage stability. Due to its fine crystallinity potassium peroxydisulfate tends to lump and can be optionally supplied with an addition of silicic acid.
