Industrial Uses

1. Fabric Solutions

  • Discharge Printing Agent: SFS is widely used in discharge printing of textiles, especially for removing dyes in specific areas to create patterns.
  • Bleaching Agent: Acts as a gentle reducing bleach for synthetic and natural fibers without damaging the fabric structure.
  • Color Stripping: Helps in removing color from dyed fabrics during re-dyeing processes.
  • Bleaching and Dehairing: Used in leather processing for controlled bleaching and softening hides without affecting strength.
  • Reducing Agent in Tanning: Assists in chrome tanning by stabilizing chromium salts and improving penetration.

2. Polymer & Resins

  • Polymerization Initiator: Used in redox polymerization processes, particularly in the production of emulsion polymers like PVC, SBR, and acrylates.
  • Chain Transfer Agent: Controls molecular weight during polymer formation, enhancing flexibility and softness in the final product.

3. Paper & Pulp Solutions

  • Deinking Agent: Applied in the recycling of paper to remove inks effectively.
  • Bleaching: Mild reducing bleach to brighten pulp without chlorine-based chemicals.

4. Performance Chemicals

  • Reducing Agent: Serves as a powerful reducing agent in various chemical reactions, especially where mild and selective reduction is needed.
  • Sulfonating Agent: Used in certain reactions requiring sulfonation under mild conditions.

5. Water Treatment

  • Dechlorination Agent: Neutralizes excess chlorine or hypochlorite in water, especially in wastewater from textile and paper industries.
  • Oxygen Scavenger: Helps in removing dissolved oxygen in water systems to prevent corrosion in boilers.
