Description

Potassium Persulfate is a powerful inorganic oxidizing agent with the formula K₂S₂O₈. Its strong oxidizing properties make it a critical initiator and reactant in a wide range of industrial polymerization and chemical synthesis processes. This compound is essential for manufacturers in the polymer, electronics, and water treatment industries seeking a reliable and efficient source of persulfate ions.

Application

  • Polymerization Initiator: A key component for initiating the emulsion polymerization of monomers like styrene, acrylonitrile, and vinyl acetate, crucial for producing synthetic rubbers, resins, and latex.
  • Printed Circuit Board (PCB) Manufacturing: Used in micro-etching and cleaning solutions to prepare copper surfaces for lamination and plating, ensuring strong adhesion.
  • Hair Bleaching & Cosmetic Formulations: Serves as the active oxidizing agent in hair bleach powders and lighteners for professional and consumer cosmetic products.
  • Soil Remediation & Oxidative Treatment: Employed in advanced oxidation processes (AOPs) for in-situ chemical oxidation (ISCO) to degrade organic contaminants in soil and groundwater.
  • Textile Desizing & Bleaching: Acts as a low-temperature bleaching agent for textiles and a desizing agent for removing starch from fabrics.
  • Disinfectant & Cleaner Component: Found in formulations for industrial and institutional cleaners where its oxidative power aids in stain removal and sanitization.
  • Laboratory Reagent: Used in analytical chemistry and research as a standard oxidizing agent for redox titrations and synthetic reactions.

Quality Control

Our Potassium Persulfate is manufactured under a stringent quality management system. Each batch is tested to ensure it meets precise specifications for purity, active oxygen content, and impurity profiles. A comprehensive Certificate of Analysis (COA) documenting results for assay, heavy metals, chloride, and other critical parameters is provided with every shipment to guarantee consistency and traceability for your processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent caking and decomposition. Incompatible with combustible materials, reducing agents, and strong bases. Observe all local regulations for storing oxidizing agents.
