Application Fields
Polymerization Initiator
  • Acrylic Emulsion Polymerization: As low-temperature initiator, dosage 0.1-0.5%, polymerization temperature 40-60℃
  • Styrene-Acrylic Emulsion Synthesis: Forms redox system with sodium bisulfite, initiates polymerization at room temperature
  • PVC Suspension Polymerization: Replaces part of hydrogen peroxide, improves polymerization rate and molecular weight distribution uniformity
Electronics Industry
  • PCB Board Etchant: Used for micro-etching of copper foil surface, concentration 50-100g/L, temperature 30-50℃
  • Semiconductor Cleaning: Removes organic contaminants from silicon wafer surface, better effect with UV activation
  • Electronic Component Pre-plating Treatment: Activates metal surface, improves coating adhesion
Environmental Treatment
  • Wastewater Advanced Oxidation: Generates sulfate radicals after activation, degrades refractory organic pollutants
  • Soil Remediation: In-situ chemical oxidation for organic contaminated soil
  • Swimming Pool Disinfection: As alternative to chlorine agents, reduces trihalomethane formation
