Characteristics

Minimum concentration of 98,5% m/m NaOH

Properties

Caustic soda lye is produced using membrane technology, concentrated up to the flake form using steam. The addition of caustic soda to liquid will cause a rise in temperature. If caustic soda becomes concentrated in one area, or is added too rapidly, or is added to hot or cold liquid, a rapid temperature increase can result in dangerous mists or boiling and spattering, which may cause an immediate violent eruption.

Applications

  • Acid neutralisation
  • Manufacture of sodium salts
  • Petroleum refining
  • Rayon manufacture
  • Rubber reclamation
  • Manufacture of plastics
  • Manufacture of soaps and detergents
  • Pulp and paper industry
  • Dyes and pharmaceutical industries
  • Aluminium processing
