Description of potassium persulphate
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.

Application:
1. Polymerization: Initiator for the emulsion or solution Polymerization of acrylic monomers, vinyl acetate, vinyl chloride etc. and for the emulsion co-polymerization of styrene, acrylonitrile, butadiene etc.
2. Metal treatment: Treatment of metal surfaces(e.g.in the manufacture of semiconductors; cleaning and etching of printed circuits), activation of copper and aluminium surfaces.
3. Cosmetics: Essential component of bleaching formulations.
4. Paper: modification of starch, repulping of wet - strength paper.
5. Textile: Desizing agent and bleach activator - particularly for cold bleaching.
