Description
Sodium Persulfate is a white, crystalline, odourless salt or crystalline powder with the density of 2.59 g/cc. 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 a particularly good storage stability as a result of its extremely high purity and of being easy and safe to handle.

Storage
NaPS (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. It must not be contact with organic matter, rust, metal and reductant matter in order to avoid catalytic decomposition and explosion. 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 NPS(SPS) as damp powder or aqueous solution has a bleaching and slightly corroding effect.
