Sodium Persulfate SPS

Sodium persulfate, abbreviated as SPS, with the chemical formula Na₂S₂O₈, is another important member of the persulfate family. It is a strong oxidizing agent and free radical initiator, but its specific applications are influenced by the properties of its sodium salt.

Main Application Areas

Polymer Chemicals: As an initiator for emulsion/solution polymerization of monomers such as acrylates, styrene, and vinyl acetate, particularly suitable for systems requiring rapid dissolution and reaction.

Textile Printing and Dyeing: Used as a desizing agent, bleaching agent, and auxiliary agent for dye oxidation and color development.

Electronics Industry: Used for micro-etching, adhesive removal, and cleaning of printed circuit boards (PCBs).

Water Treatment: Used as an oxidizing bactericide and organic pollutant degrader, especially suitable for advanced wastewater oxidation treatment.

Other Applications: Metal surface treatment, soil remediation, cosmetics (small amounts used as oxidants), and laboratory reagents.
