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.
PACKAGING, STORAGE & SHELF LIFE :
25 kgs and 1000 kgs net polyethylene and polypropylene bags. 1000 kgs bag has antistatic properties. It must be stored in well closed original packing and protected from direct sunlight, heat and humidity. Impurities such as dirt, rust or traces of metal and reductants may cause catalytic decomposition. It can be stored for 24 months below 30°C. The product as supplied or in solution needs to be handled with appropriate care. The eye, skin and clothes must be protected when working with PPS as damp powder or aqueous solution has a bleaching and slightly corroding effect.
SAFETY & PRECAUTIONS :
Avoid contact with eyes, skin and clothing. Use with adequate ventilation. Do not swallow. Avoid breathing vapors, mists or dust. Do not eat, drink or smoke in work area. Prevent contact with combustible or organic materials. Label containers and keep them tightly closed when not in use. Wash thoroughly after handing. For drinking water applications, the optimum dosing must be max. 43 mg/L.
