Description

Sodium Persulfate is a powerful, versatile inorganic oxidizer essential for numerous industrial and chemical synthesis processes. Its high oxidation potential and water solubility make it a critical reagent for initiating polymerization, etching, and advanced oxidation treatment systems. This product is indispensable for manufacturers and processors in the electronics, polymer, water treatment, and textile industries seeking a reliable and effective oxidizing agent.

Application

• Polymerization Initiator: A key component for initiating the emulsion or solution polymerization of monomers like acrylonitrile, styrene, and vinyl acetate.
• Printed Circuit Board (PCB) Manufacturing: Used as an etchant and micro-etchant for copper surfaces and as a cleaning agent to remove organic contaminants.
• Environmental Remediation & Water Treatment: Employed in advanced oxidation processes (AOPs) to degrade organic pollutants and for soil remediation via in-situ chemical oxidation (ISCO).
• Hair Bleaching & Cosmetic Formulations: Serves as the primary oxidizing agent in hair bleach, lighteners, and other cosmetic products.
• Textile & Pulp Bleaching: Used for bleaching textiles and as a delignifying agent in pulp processing.
• Metal Surface Treatment: Applied for cleaning, pickling, and activating metal surfaces prior to plating or coating.
• Chemical Synthesis: A valuable oxidizing agent in organic synthesis for reactions such as the oxidation of alcohols and the cleavage of glycols.
• Disinfectant & Cleaner Component: Incorporated into formulations for industrial and institutional disinfectants and cleaners.

Quality Control

Our Sodium Persulfate is manufactured under stringent 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 key parameters are provided to guarantee consistency and performance for your critical applications.

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. Observe local regulations for the storage of oxidizing agents.
