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.

Please refer to MSDS for detailed information on Storage & Handling.

Sodium Persulfate (NaPS/SPS) is a stable, strong oxidising agent and it generates excellent free radical in aqueous media. AMINISHA offers the product in the form of a colourless, odourless, crystalline powder. NaPS/SPS from AMINISHA has good storage stability and enables safe handling due to its high purity and low water content.

NaPS/SPS can decompose under unfavourable conditions due to high it’s oxidation potential. The product is not flammable but has a fire-promoting effect as it releases oxygen.
