Product Description
Potassium Persulfate K₂S₂O₈ 99% - Polymer Initiator, PCB Etchant & Bleaching Agent
Potassium persulfate (K₂S₂O₈) is a high-performance strong oxidizing agent within the persulfate family. This high-purity (99%) white crystalline powder or granules offers superior aqueous solution stability compared to its ammonium counterpart. It efficiently decomposes under heat or specific conditions to generate highly reactive sulfate radicals (SO₄⁻*), making it indispensable for polymer synthesis, electronics manufacturing, textile bleaching, and environmental remediation.
Core Applications & Technical Advantages
Polymer Industry Initiator
- Essential water-soluble initiator for emulsion and solution polymerization
- Efficiently initiates free-radical polymerization of acrylates, styrene, acrylonitrile, and vinyl acetate
- Core raw material for acrylic emulsions, styrene-acrylic emulsions, styrene-butadiene latex, and polyacrylamide flocculants
- Potassium salt formulation eliminates odor and nitrogen interference issues
Electronics Manufacturing Etchant
- High-stability, precision copper micro-etchant for PCBs and semiconductor packaging
- Provides uniform, controllable etching rates and consistent micro-roughness
- Creates ideal bonding surfaces for electroless copper plating, electroplating, and lamination
- Critical for high-density interconnect (HDI) boards and high-reliability components
Textile & Chemical Processing
- Core component of low-temperature, high-efficiency bleaching activators
- Superior oxidation potential reduces energy consumption and fiber damage
- Effective for hair bleaching, fat/oil decolorization, and selective oxidation syntheses
Environmental Remediation
- Preferred agent for Persulfate-based Advanced Oxidation Processes (PS-AOPs)
- Generates sulfate and hydroxyl radicals to degrade stubborn pollutants
- Effective against petroleum hydrocarbons, chlorinated organics, pesticides, and antibiotics
