High Purity Potassium Persulphate 7727-21-1 | Reliable Supplier

Potassium Persulphate (also spelled as potassium persulfate or even sometimes mis-typed as potasium persulphate) is a white, crystalline, inorganic compound with the chemical formula K₂S₂O₈. Identified by its CAS number 7727-21-1, this high-purity oxidizing agent plays a fundamental role across industries, from polymerization initiators in plastics, etching agents in electronics, to powerful cleaning and bleaching in the textile and paper sectors (ScienceDirect: Potassium Persulfate).

This page reviews its chemical parameters, latest industrial trends, advanced application scenarios, product data, and answers to technical questions — to support informed sourcing and application decisions.

The potassium persulphate market is projected to see moderate but steady growth, thanks to increasing demand in electronics, water treatment, polymer production, and environmental applications. According to MarketsandMarkets, the Asia-Pacific region dominates due to strong manufacturing infrastructure and rapid urbanization. Environmental regulations are also driving the need for high purity persulphates as green oxidants (Ref: Royal Society of Chemistry: Emerging uses of persulfate).

• Polymer industry adopts potassium persulphate as an efficient initiator in emulsion polymerization.
• Semiconductor and electronics etching increasingly rely on high-grade, ultra-low metal persulfates.
• The textile and paper industries require premium, impurity-controlled potassium persulfate for bleaching and fabric treatment.
• Ongoing innovation in soil remediation and water treatment leverages its strong oxidative capability.

• Polymer Industry: Used as a radical initiator in emulsion polymerization — e.g., in the synthesis of PVC, polyacrylamide, acrylates, SBR latex.
• Electronics/PCB Manufacturing: High-purity potassium persulphate serves as a copper etchant for precise patterning.
• Textile & Paper Bleaching: Efficient, residue-free bleaching and desizing agent, improving fabric brightness without harsh chlorine.
• Cosmetics and Hair Care: Used as a bleach in professional hair coloring products (strictly regulated, must adhere to ECHA safe limits).
• Soil & Water Remediation: Promotes advanced oxidation processes—removes organic pollutants, oil spills, and persistent contaminants (DOI:10.1016/j.jhazmat.2019.121134).
• Mining Industry: Used in ore flotation and in gold extraction processes as a powerful oxidant.
• Other Uses: Photoengraving, analytical reagent, explosives, rubber hardening, and more, highlighting versatility (PubChem Potassium Persulfate).

For occupational safety, Potassium Persulphate SDS (Safety Data Sheet) compliance is compulsory. Refer to our up-to-date SDS sheet: Download SDS. Key safety aspects:

• Store in a cool, dry, ventilated area away from combustibles.
• Avoid inhalation or skin contact: use gloves, goggles, and local exhaust where dust is present.
• Decomposes at high temperatures, releasing oxygen—a potential fire hazard when mixed with organics.
• Flush spillages with ample water; do not mix with strong acids or reducing agents (see details in SDS (SDS PDF)).

• State-of-the-art synthesis and strict QC assure >99% purity with controlled trace metals and excellent particle size distribution.
• Full documentation: COA, latest potassium persulfate SDS, technical/analytical support.
• Custom packaging (1kg, 10kg, 25kg, jumbo bags), labeling, and logistics by sea or air.
• Responsive technical support team: james@fizachem.com | Tel: 0086-311-87718167
• Excellent track record with global customers in polymers, electronics, advanced manufacturing.
