About the Product

  • Solid Caustic Soda

    Caustic soda flakes are the solid, white form of sodium hydroxide, produced as dry, odorless flakes. This product is obtained by evaporating high-purity liquid caustic soda and is preferred in many industries due to its easier storage, safer transportation, and long shelf life. Caustic soda flakes are typically produced with a purity of over 98% and are packaged in moisture-resistant packaging.

  • Liquid caustic soda

    Liquid caustic soda is a clear, colorless solution of sodium hydroxide in water, typically offered in concentrations ranging from 30% to 50%. This form is easily injected into industrial processes and reacts quickly. Its liquid state makes it ideal for applications requiring fast and uniform mixing. Transportation is usually carried out in specialized tankers to ensure safety and maintain product quality.

Difference Between Liquid and Solid Caustic Soda

While caustic soda Flakes , due to its high purity, is widely used in chemical industries, paper production, and detergents, the liquid form is preferred in continuous processes and automated production lines for its ease of mixing and injection. The choice between the two depends on the specific process requirements and safety standards of each industry.

Applications of Caustic soda

  • Paper and Pulp Production

    Caustic soda is used in the process of separating cellulose fibers from lignin and plays a vital role in bleaching and preparing pulp.

  • Petrochemical and Oil Refining Industries

    In these industries, caustic soda is used to remove acidic compounds, sulfur, and corrosive impurities from oil and gas streams.

  • Detergent and Soap Production

    Sodium hydroxide is used in the saponification reaction of fats with oils and plays a key role in the production of solid soaps and certain industrial detergents.

  • Water and Wastewater Treatment

    Caustic soda is used in water treatment to adjust pH, neutralize acids, and aid in the precipitation of heavy metals in industrial processes.

Other Applications

Textile and dyeing industries, aluminum production, food industry, pharmaceuticals, plastic manufacturing, metal and electroplating industries
