Primary Applications
PCB Etchant for Electronics Manufacturing
In printed circuit board production, our ACS Grade Sodium Persulfate serves as a precision etchant for copper-clad laminates. It oxidizes and dissolves exposed copper with exceptional uniformity, creating clean, well-defined circuit paths essential for high-density interconnect boards. The aqueous solutions offer superior stability and control while decomposing into environmentally favorable sulfate byproducts.
Polymerization Initiator
As a thermal initiator in polymer science, the ACS Grade purity is critical for predictable polymerization rates and consistent molecular weight distributions. It generates sulfate radical anions upon heating to initiate free-radical polymerization of monomers including acrylamide, vinyl acetate, and methyl methacrylate. This makes it indispensable for producing polyacrylamide gels, specialty adhesives, water-soluble polymers, and acrylic resins with precisely controlled properties.
