Deskripsi produk
Potassium Persulfate K₂S₂O₈ 99% - Polymer Initiator, PCB Etchant & Bleaching Agent
Potassium persulfate (K₂S₂O₈) is a high-purity (99%) white crystalline powder or granules that serves as an exceptional strong oxidizing agent. Its aqueous solution offers superior stability and efficiently decomposes under heat or specific conditions to generate highly reactive sulfate radicals (SO₄⁻*). This chemical property makes it indispensable in cutting-edge applications including polymer synthesis, electronics manufacturing, textile bleaching, and environmental remediation.
Core Applications
Polymer Industry Initiator
Potassium persulfate is a primary water-soluble initiator in emulsion and solution polymerization. It efficiently initiates free-radical polymerization of monomers including acrylates, styrene, acrylonitrile, and vinyl acetate. As a core technical raw material, it's essential for producing high-grade products such as acrylic emulsions, styrene-acrylic emulsions, styrene-butadiene latex, and polyacrylamide flocculants. The potassium salt formulation avoids potential odor and nitrogen interference associated with ammonium salts, making it ideal for synthesis scenarios with stringent purity requirements.
Electronics Manufacturing Etchant
In printed circuit board (PCB) manufacturing and semiconductor packaging, potassium persulfate serves as a high-stability, precision copper micro-etchant. Its solution provides stable chemical properties and uniform, controllable etching rates. It creates activated copper surfaces with ideal micro-roughness for perfect bonding interfaces in subsequent processes like electroless copper plating, electroplating, or lamination. This is crucial for ensuring performance in high-density interconnect (HDI) boards and high-reliability electronic components.
Textile and Chemical Processing
In textile dyeing and printing, potassium persulfate is a core component of low-temperature, high-efficiency bleaching activators. The sulfate radicals it generates have higher oxidation potential than traditional bleaching agents, enabling efficient decolorization and bleaching of cotton, linen, and blends at lower temperatures. This significantly reduces energy consumption and fiber damage. Additional applications include hair bleaching, fat/oil decolorization, and selective oxidation in chemical syntheses.
Environmental Remediation
As a preferred agent for Persulfate-based Advanced Oxidation Processes (PS-AOPs), potassium persulfate shows great potential in soil and groundwater remediation and treatment of recalcitrant organic wastewater. When activated by heat, alkali, UV light, or transition metal ions, it generates highly oxidizing sulfate and hydroxyl radicals that non-selectively degrade stubborn pollutants including petroleum hydrocarbons, chlorinated organics, pesticides, and antibiotics.
Product Specifications
This product is graded based on purity, active oxygen content, aqueous solution stability, and heavy metal impurity content into Industrial Grade, Reagent Grade, and Electronic Grade. The Electronic Grade has particularly strict controls for impurities like chloride and sodium ions.
Safety and Handling
Potassium persulfate is a strong oxidizing agent. Mixing with reducing agents, organic materials, or metal powders may form explosive mixtures. Store away from heat sources and ignition sources in a cool, dry place. Wear appropriate protective equipment during handling to avoid dust inhalation.
Our potassium persulfate products feature high purity, good solubility, stable reactivity, and excellent batch-to-batch consistency. We provide customized products and professional application solutions to polymer synthesis companies, PCB manufacturers, environmental engineering firms, textile dyeing mills, and research institutions, helping clients maintain technological leadership through process innovation.
