High-purity caustic soda meeting stringent industrial-grade compliance standards for consistent process performance.
Available in multiple forms including 50% aqueous solution and solid flakes to suit diverse handling and dosing requirements.
Manufactured under strict quality control with traceable batch documentation for regulatory and safety assurance.
Low levels of heavy metal impurities (e.g., Fe, Ni, Pb) ensuring minimal catalytic interference in sensitive chemical syntheses.
Stable shelf life when stored properly, maintaining concentration and reactivity over extended periods.
Pulp and paper manufacturing — used in kraft pulping and bleaching processes.
Chemical synthesis — essential for saponification, neutralization, and pH adjustment in organic and inorganic production.
Water treatment — employed for pH correction, heavy metal precipitation, and coagulant aid in municipal and industrial wastewater systems.
Aluminum oxide production — key reagent in the Bayer process for bauxite digestion.
Textile processing — applied in mercerization of cotton and dye-house effluent neutralization.
