Sodium Hydroxide Solid 99% - Caustic Soda Flakes & Pellets

Product Overview & Performance

Sodium hydroxide solid (99% pure NaOH), commonly known as caustic soda, is a widely utilized high-purity inorganic base serving as a fundamental raw material across global manufacturing sectors. Appearing as odorless, bright white flakes or spherical pellets, it exhibits exceptional hygroscopic properties and dissolves rapidly in water through a strongly exothermic reaction to yield a powerful, highly alkaline solution.

By selecting high-purity solid caustic soda over pre-diluted liquid forms, chemical operators significantly reduce long-distance shipping volumes and freight expenses while extending product shelf life. This solid format allows precise on-demand concentration blending, optimizing process efficiency across pulp and paper processing, soap and detergent manufacturing, alumina refining, water treatment, and chemical synthesis.

Technical Specifications (Certificate of Analysis Highlights)

Primary Industrial Applications

• Soap & Detergent Manufacturing: Acts as the primary saponification reagent for hand soaps, commercial bar soaps, and heavy-duty degreasing powders.

• Water & Wastewater Treatment: Highly effective for rapid neutralization of acidic industrial effluent, municipal pH adjustment, and heavy metal precipitation.

• Pulp & Paper Processing: Vital for wood chip delignification in Kraft pulping processes, paper pulp bleaching, and fiber de-inking during recycling.

• Textile Processing & Mercerization: Utilized in cotton fiber treatment to enhance fabric strength, lustrous appearance, and dye absorption capability.

• Chemical Synthesis & Alumina Extraction: Serves as a core chemical intermediate in the Bayer process for alumina extraction and the synthesis of organic sodium compounds.

Key Commercial Advantages

1. Cost-Effective Logistics: Concentrated solid format minimizes freight expenses per unit of active active substance compared to liquid bulk.

2. High Chemical Purity: Low levels of iron and chloride impurities prevent scaling and undesirable side-reactions in sensitive chemical synthesis.

3. Moisture-Resistant Packaging: Sealed in heavy-duty 25kg PE-lined woven bags or 1000kg UN-certified jumbo bags to prevent deliquescence during transit.

4. Complete Export Documentation: Fully supported with Material Safety Data Sheets (MSDS/SDS), Certificate of Analysis (COA), and DG shipping certificates.

• Handling & Storage Guidelines

  • Personal Protection & Safety: Sodium hydroxide solid (caustic soda) is extremely corrosive to human tissue, causing severe chemical burns upon contact and severe eye damage. Dilution and handling generate significant exothermic heat, increasing the risk of thermal splashes. Full personal protective equipment (PPE) is strictly required, including chemical splash goggles, a full-face shield, heavy-duty neoprene or nitrile rubber gloves, an apron, and alkali-resistant protective clothing. Avoid breathing dust or vapors; use local exhaust ventilation or suitable respiratory protection when handling bulk solid quantities.

  • Storage Environment & Protocols: Store in a cool, dry, well-ventilated warehouse with dedicated containment away from direct sunlight and sources of heat or moisture. Keep containers tightly sealed in their original moisture-impermeable packaging when not in use to prevent atmospheric carbon dioxide absorption and rapid caking. Isolate strictly from strong acids, organic chemicals, halogenated hydrocarbons, and active metals like aluminum, zinc, and tin, as reactions can produce hazardous conditions or flammable hydrogen gas. Ensure spill containment kits and emergency eyewash stations are immediately accessible.
