Sodium persulfate is a white, crystalline, odourless salt. It is used as initiator for the Polymerization of monomers and as a strong oxidizing agent in many applications. It has the particular advantage of being almost non-hygroscopic, of having particularly good storage stability as a result of its extremely high purity and of being easy and safe to handle.

Storage

SPS is not combustible but assists combustion materials due to release of oxygen. Provided it is stored under appropriate condition. It must be stored dry in closed containers and protected from direct sunlight, heat and humidity. Impurities such as dirt, rust or traces of metal and reductants may cause catalytic decomposition. 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 SPS as damp powder or aqueous solution has a bleaching and slightly corroding effect. Recommended storage temperature: normal temperature. Storage stability as from date of delivery: 12 months.
