Sodium Hydroxide 99% | High-Purity Caustic Soda Pearls

Key Features & Technical Advantages

• High Purity Assurance: Engineered with a guaranteed minimum chemical assay of 99.0%, featuring ultra-low trace impurity levels—specifically minimized sodium carbonate (Na2CO3), heavy metals, and iron content. This exceptionally clean formulation guarantees predictable reaction kinetics and high yield, completely preventing unwanted side reactions, solution discoloration, or catalyst poisoning during high-precision chemical processing.

• Rapid & Uniform Dissolution: Features a consistent, low-dust pearl or flake morphology designed for optimal flowability and non-caking behavior. The solid dissolves rapidly in water through a strongly exothermic reaction, releasing thermal energy that speeds up batch mixing cycles and significantly improves solution preparation efficiency for high-capacity industrial systems.

• Multi-Layer Protective Packaging: Enclosed in heavy-duty, double-layer moisture-proof polyethylene/polypropylene (PE/PP) woven bags containing tight inner liners (25 kg/bag). This specialized multi-barrier system effectively isolates the product from ambient air, atmospheric moisture, and carbon dioxide, successfully preventing deliquescence, clumping, and chemical degradation during long-distance maritime transport and extended warehouse storage.

Primary Industrial Applications

• Soap & Detergent Manufacturing: Serves as a fundamental, high-potency raw material for saponification reactions. By chemically hydrolyzing ester bonds in natural fats, tallow, and vegetable oils, it yields premium-grade solid soaps, liquid detergent bases, and specialized industrial anionic surfactants.

• Water & Wastewater Treatment: Extensively deployed across municipal sewage treatment plants and industrial effluent facilities. It acts as a fast-acting alkaline agent for precise pH adjustment, neutralizing acidic waste streams, controlling pipeline corrosion, and inducing heavy metal ion precipitation prior to environmental discharge.

• Pulp, Paper & Textile Processing: Essential for Kraft pulping operations, where it breaks down and removes lignin from wood chips to release clean cellulose fibers for high-grade paper manufacturing. In the textile sector, it is used for cotton scouring and mercerization under tension, permanently enhancing fiber tensile strength, dye uptake, and surface luster.

• Chemical Synthesis & Refining Operations: Extensively applied as a core reactive base in the Bayer process for alumina extraction from bauxite ore, petroleum product refining and desulfurization, organic synthesis, and the production of downstream sodium salts.
