Potassium persulfate, abbreviated as KPS, with the chemical formula K₂S₂O₈, is an important strong oxidizing chemical and a polymer polymerization initiator.
Main Application Areas
Polymer Chemicals (Core Use): Its most important application is as an initiator for emulsion or solution polymerization of olefin monomers (such as styrene, acrylates, vinyl acetate, etc.), widely used in synthetic resins, adhesives, coatings, and other fields.
Water Treatment: Used as an oxidizing biocide in circulating cooling water systems, effectively controlling algae and microorganisms.
Textiles and Papermaking: Used as a desizing agent and bleaching agent in fabric bleaching and papermaking processes.
Electronics Industry: Used for micro-etching and cleaning of printed circuit boards (PCBs).
Other Applications: Used as a small additive in cosmetics (e.g., as an oxidizing agent in some hair dyes), and also in metal processing, wastewater treatment, etc.
