High-Purity Caustic Soda Solid (NaOH) 99% for Critical Industrial Processing

Caustic Soda Solid (NaOH), chemically known as Sodium Hydroxide, is an indispensable inorganic strong base and foundational chemical building block across modern manufacturing sectors. Characterized by its appearance as white, highly translucent crystalline solids—available in uniform flakes or spherical pellets—it exhibits strong corrosive properties, rapid water solubility, and high hygroscopicity. When dissolved or reacted, it neutralizes acidic process streams rapidly while generating significant exothermic heat, driving reaction kinetics efficiently.

Premium Purity & Technical Advantages

Our industrial-grade 99% Caustic Soda Solid is refined through stringent, state-of-the-art chlor-alkali production processes to maintain exceptional chemical consistency. By enforcing strict quality controls, the product maintains ultra-low impurity levels of sodium carbonate (Na2CO3), sodium chloride (NaCl), and trace heavy metals like iron (Fe). This high level of chemical purity prevents unexpected side-reaction byproducts, protects process equipment against scaling, and satisfies the demanding standards of high-precision industrial chemistry.

Diverse Industrial Applications

• Pulp & Paper Processing: Essential for dissolving lignin in Kraft pulping processes and bleaching paper fibers.

• Soap & Detergent Manufacturing: Serves as the primary saponifying base to convert fats and oils into soap salts and commercial surfactants.

• Chemical Synthesis & Metallurgical Refining: Acts as a vital reagent in bauxite digestion for alumina extraction (Bayer process), organic chemical synthesis, and petroleum desulfurization.

• Water Treatment & Effluent Control: Provides rapid pH neutralization and facilitates heavy metal precipitation in industrial wastewater treatment.

To guarantee product stability during ocean transit and long-term storage, our solid NaOH is packed in heavy-duty, PE-lined moisture-proof 25kg bags or UN-rated bulk containers, preventing atmospheric moisture absorption and deliquescence.
