Pure NaOH Sodium Hydroxide | 99% Flakes & Pearls Bulk

Pure NaOH Sodium Hydroxide | 99% Flakes & Pearls Bulk

Product Attributes :

High-grade NaOH sodium (sodium hydroxide) engineered for chemical synthesis, industrial water treatment, and large-scale manufacturing. As an established global exporter, we supply 99% pure anhydrous NaOH sodium in both uniform flake and prilled pearl forms, delivering maximum alkaline strength, rapid dissolution rates, and exceptional chemical purity.

Manufactured in ISO 9001-certified facilities, our NaOH sodium undergoes strict batch testing to maintain low iron levels and minimal sodium carbonate ( $\text{Na}_2\text{CO}_3$ ) content. It serves as a vital reagent across numerous industries, including soap saponification, pulp and paper pulping, textile processing, and alumina extraction.

We provide secure export packaging designed for hazardous chemical transport, including 25kg multi-wall polypropylene bags with inner PE liners and 1,000kg jumbo tote containers. Supported by complete safety documentation (MSDS/SDS) and batch-specific Certificates of Analysis (COA), we ensure seamless shipping and direct factory pricing.

Core Product Advantages

High Chemical Potency (≥ $\ge 99\%$ Assay): Manufactured using advanced membrane-cell technology to achieve an ultra-high purity level of at least 99%. This concentrated chemical strength guarantees rapid, highly predictable reaction rates, eliminates unreacted raw material waste, and maximizes overall yield in complex organic and inorganic chemical synthesis processes.
Rapid Exothermic Dissolution: Dissolves swiftly and completely in aqueous media through a strongly exothermic dissolution process. The immediate release of thermal energy accelerates mixing cycles, reduces external mechanical heating costs, and leaves zero insoluble residue or unreacted sediment to clog automated dosing pumps and pipeline networks.
Hermetic Moisture-Barrier Protection: Encapsulated in heavy-duty, multi-wall bags featuring an extra-thick high-density polyethylene (HDPE) inner liner. This airtight protective barrier shields the highly hygroscopic material from ambient humidity and carbon dioxide ( $\text{CO}_2$ ) absorption, completely preventing product caking and preserving long-term reactivity during extended maritime shipping and warehouse storage.
Consistent Flowability & Dust-Free Formulations: Engineered into uniform prilled pearls and thin flakes that naturally resist physical clumping. Their optimized bulk density and particle consistency protect workers from airborne particulate hazards while enabling smooth, non-clogging pneumatic transport and automated hopper dosing.
Strict Quality Assurance & Traceability: Produced under ISO-certified quality management standards to deliver batch-to-batch consistency. Each shipment includes a batch-specific Certificate of Analysis (COA) and a comprehensive SDS, ensuring full regulatory compliance and seamless integration into automated industrial production lines.

Primary Industrial Applications

Soap & Detergent Manufacturing: Serves as the fundamental saponification reagent (lye) to chemically convert natural fats, vegetable oils, and fatty acids into commercial bar soaps, liquid cleansers, laundry detergents, and heavy-duty industrial degreasers with consistent bar hardness and lather performance.
Pulp, Paper & Packaging Processing: Essential in the Kraft pulping process for digesting raw wood chips, dissolving unwanted lignin binders, and separating pure cellulose fibers. It produces high-tensile paper pulp required for durable packaging materials, paperboard, and fine writing paper.
Water & Wastewater Treatment: Functions as a primary alkaline dosing agent in municipal water purification plants and industrial effluent treatment facilities. It accurately regulates pH levels, neutralizes acidic wastewater streams, and precipitates toxic heavy metal ions ( $\text{Fe}^{3+}$ , $\text{Cu}^{2+}$ , $\text{Pb}^{2+}$ , $\text{Zn}^{2+}$ ) for safe filtration and environmental discharge compliance.
Textile & Dyeing Industry: Widely applied in cotton mercerization, fabric scouring, and dye bath preparation. It swells natural cotton fibers, significantly improving fabric tensile strength, dimensional stability, surface sheen, and color absorption capacity.
Alumina Refining & Metallurgy: Extensively utilized in the Bayer process to dissolve crude bauxite ore under high temperatures and pressures, extracting pure alumina ( $\text{Al}_2\text{O}_3$ ), which serves as the direct precursor for aluminum metal smelting.
