Product Detail

Product Tags

Potassium persulphate is a white crystalline, odorless powder ,the density of 2.477.It can be decomposed about 100°C and dissolved in the water not in ethanol, and has strong oxidation. It is used to produce detonator, bleacher, oxidant and initiator for the Polymerization. It has the particular advantage of being almost non-hygroscopic of having a good storage stability in normal temperature and of being easy and safe to handle.
