High Purity 99% Sodium Persulfate Powder for PCB Etching and Polymerization Initiation

Sodium persulfate is mainly used as bleaching agent, oxidant and lotion polymerization accelerator. Its hazard symbols are marked as O and Xn, involving risk terms such as R8, R22, R36/37/38, R42/43, and safety terms including S17, S26, S36/37/39, S45.

This product is our flagship high-purity Sodium Persulfate (Na₂S₂O₈), meticulously processed to achieve a consistent purity of 99% or higher. It is presented as a fine, free-flowing white crystalline powder, optimized for both precise laboratory applications and demanding large-scale industrial processes.

The exceptional purity minimizes the presence of metallic impurities and other contaminants, making it an indispensable reagent for analytical chemistry, where it serves as a powerful and reliable oxidizing agent in titrations and quantitative analyses. In industrial settings, its high-grade quality ensures predictable and efficient reaction kinetics, which is critical for maintaining product consistency and yield.

The dual utility of this powder is a key selling point. For Laboratory Grade use, it meets stringent specifications for research and development, pharmaceutical synthesis, and quality control labs. Scientists value its batch-to-batch consistency for experiments involving radical initiation or redox chemistry.

For Industrial Grade applications, its robustness shines in sectors like electronics, where it's used for advanced PCB (Printed Circuit Board) micro-etching and cleaning copper surfaces with high precision. The fine powder form ensures rapid dissolution and uniform reaction in aqueous solutions, a vital characteristic for processes like polymer synthesis, where it acts as an initiator for emulsion polymerization of styrene, acrylonitrile, and other monomers, controlling polymer chain growth and molecular weight.

Furthermore, its role extends into environmental technology. As a source of powerful sulfate free radicals (SO₄•−), this high-purity sodium persulfate is employed in advanced oxidation processes (AOPs) for soil and groundwater remediation. It effectively degrades persistent organic pollutants, chlorinated solvents, and petroleum hydrocarbons where other oxidants fail.

The 99% purity guarantees maximum active oxidant delivery, making remediation projects more effective and cost-efficient. We ensure seamless supply for bulk industrial users, with packaging options ranging from secure 25 kg drums for factory use to smaller, lab-friendly 500g bottles, all designed to preserve product integrity by protecting it from moisture and contamination.
