Product Short Description: Potassium persulfate is a white, finely crystalline, odourless salt consisting of Product Description: Potassium Persulfate is a white, finely crystalline, odourless salt consisting of technically pure potassium peroxodisulfate and silicic acid to enhance the free flowing properties. It is used as an initiator (source of free radicals) for the polymerisation of monomers and as a strong oxidising 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 peroxodisulfate tends to lumping.
