China and the United States are the leading exporters of sodium persulfate, accounting for a substantial majority of global shipments, while Germany, South Korea, and India represent the largest importers. Sodium persulfate prices have remained relatively stable amid steady cross-border flows, reflecting consistent industrial demand in polymerization and electronics cleaning applications. Exports from China have expanded modestly over the past two years, while U.S. exports have held steady, and European imports—particularly by Germany—have shown resilience despite broader chemical trade volatility.
Sodium persulfate is a white, crystalline, odorless solid that is highly soluble in water and decomposes before melting (typically above 100 °C). It is an inorganic peroxide and a strong oxidizing agent. Industrially, it serves primarily as a free-radical initiator in polymerization reactions—especially for vinyl monomers such as acrylates, styrene, and butadiene—and as a bleaching and etching agent in printed circuit board manufacturing. Its key application areas include the production of synthetic rubbers, plastics, adhesives, and water-soluble polymers, as well as in textile and hair-coloring formulations.
Sodium persulfate is used as a bleach, both standalone (particularly in hair cosmetics) and as a detergent component. It is a replacement for ammonium persulfate in etching mixtures for zinc and printed circuit boards, and is used for pickling of copper and some other metals. It is a source of free radicals, making it useful as an initiator for e.g. emulsion polymerization reactions and for accelerated curing of low formaldehyde adhesives. Sodium persulfate is also used as a soil conditioner and in manufacture of dyestuffs, modification of starch, bleach activator, desizing agent for oxidative desizing, etc.For waste processing in the photographic industry, used as a soft metal surface corrosion agents of the printed circuit board and textile desizing agents, sulfur dyes colorformer.
