Description

Sodium Persulfate is a powerful inorganic oxidizing agent with the chemical formula Na₂S₂O₈. It is valued for its high oxidation potential and stability in aqueous solutions, making it a versatile initiator and cleaner in demanding industrial processes. This compound is essential for manufacturers in the electronics, polymer, and water treatment industries seeking reliable and efficient oxidation chemistry.

Application

• Polymerization Initiator: A key component for initiating the emulsion polymerization of monomers like styrene, acrylonitrile, and vinyl acetate in the production of synthetic rubbers, resins, and plastics.
• Printed Circuit Board (PCB) Manufacturing: Used as an etchant and micro-etchant for copper surfaces to ensure optimal adhesion in the plating and solder mask processes.
• Hair Bleaching & Cosmetic Formulations: Serves as a primary oxidizing agent in hair bleach, lighteners, and other cosmetic products requiring controlled oxidation.
• Soil Remediation & Environmental Treatment: Employed in advanced oxidation processes (AOPs) for in-situ chemical oxidation (ISCO) to degrade organic contaminants in soil and groundwater.
• Metal Surface Treatment: Used for cleaning, pickling, and activating metal surfaces (e.g., copper, brass) prior to plating or painting to improve coating adhesion.
• Textile Bleaching & Desizing: Acts as a bleaching agent for textiles and a desizing agent for starches on fabrics under controlled conditions.
• Disinfectant & Pool Shock Component: Found in some specialty disinfectant formulations and pool shock products for its oxidizing and sanitizing properties.

Quality Control

Our Sodium Persulfate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, active oxygen content, and impurity profiles. Certificates of Analysis (COA) documenting these results are provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical 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, strong reducing agents, and bases. Store separately.
