High Purity Caustic Sodium 99% | Wholesale Flakes & Pearls

High Purity Caustic Sodium 99% | Wholesale Flakes & Pearls

Product Attributes :

High-grade caustic sodium (sodium hydroxide) engineered for chemical processing, water treatment, and heavy-duty manufacturing. As a trusted chemical exporter, we produce top-tier 99% pure caustic sodium in both flake and pearl forms, offering quick dissolution rates, high alkaline strength, and zero organic contaminants.

Manufactured under stringent ISO-certified quality controls, our caustic sodium delivers consistent performance for soap saponification, pulp and paper digestion, textile processing, and industrial cleaning solutions. It undergoes rigorous quality testing to ensure exceptionally low levels of sodium carbonate ( $\text{Na}_2\text{CO}_3$ ) and trace heavy metals.

We offer customized bulk export packaging, including 25kg multi-wall moisture-proof bags with polyethylene inner liners and 1,000kg jumbo tote containers. Backed by complete global safety documentation (MSDS) and batch-specific Certificates of Analysis (COA), we provide seamless international shipping at direct factory rates.

Core Product Advantages

Maximum Chemical Reactivity (≥ $\ge 99\%$ Assay): Manufactured using advanced membrane-cell electrolysis to ensure high purity and low trace impurities. This concentrated purity guarantees precise stoichiometric performance, immediate alkaline reaction rates, and maximum yields in complex organic saponification, chemical synthesis, and neutralization processes.
Superior Moisture-Barrier Packaging: Sealed in heavy-duty, double-layer bags featuring a high-density polyethylene (HDPE) inner liner. This robust moisture barrier protects the highly hygroscopic material from atmospheric humidity absorption and carbon dioxide ( $\text{CO}_2$ ) degradation, preventing product caking and extending shelf life during maritime transport.
Rapid Exothermic Dissolution: Dissolves rapidly and completely in aqueous media with strong, immediate heat generation (an exothermic dissolution process). This swift kinetic action helps accelerate mixing cycles, reduces mechanical heating requirements, and significantly lowers processing times in large-scale industrial batching operations.
Consistent Particle Size & Low Dusting: Available in uniform, dust-free pearls and thin flakes engineered for superior flowability. The consistent particle size distribution resists clumping, protects workers from airborne particulate hazards, and ensures smooth pneumatic feeding into automated hopper systems.

Primary Industrial Applications

Soap & Cosmetic Manufacturing: Acts as the primary saponification reagent (lye) to convert vegetable oils, animal tallows, and fatty acids into solid bar soaps, liquid soap bases, and commercial cleansers, ensuring consistent bar hardness, predictable lathering, and full triglyceride conversion.
Water Treatment & Environmental Protection: Functions as an effective pH neutralizer and caustic dosing agent across municipal water plants and industrial wastewater facilities. It neutralizes acidic effluent streams and assists in precipitating toxic heavy metal ions ( $\text{Fe}^{3+}$ , $\text{Cu}^{2+}$ , $\text{Pb}^{2+}$ , $\text{Zn}^{2+}$ ) for safe environmental filtration.
Pulp, Paper & Packaging Processing: Deployed in the Kraft pulping process to digest raw wood chips, dissolve unwanted lignin binders, and bleach paper pulp, yielding high-strength cellulose fibers for paperboard, packaging materials, and fine paper production.
Textile & Dyeing Industry: Widely applied in cotton mercerization, fabric scouring, and dye bath preparation. It swells natural cotton fibers to significantly enhance fabric tensile strength, surface luster, dimensional stability, and dye absorption performance.
Alumina Refining & Metal Processing: Crucial for the Bayer process, where concentrated caustic solutions dissolve crude bauxite ore at elevated temperatures and pressures to extract pure alumina ( $\text{Al}_2\text{O}_3$ ), the primary precursor for aluminum metal smelting.
