25kg Sodium Hydroxide Flakes | 99% Pure Caustic Soda

Key Product Advantages

• Industrial-Grade 99% Purity: Delivers a high-assay chemical concentration that guarantees optimal reactive strength and predictable reaction kinetics. Engineered with strictly controlled trace impurities—specifically ultra-low levels of iron, heavy metals, and sodium chloride—this high-purity material minimizes process residues, prevents unwanted side reactions, avoids catalyst poisoning, and ensures precise, reliable results across demanding manufacturing operations.

• Rapid & Complete Dissolution Rate: Specially processed into uniform solid flakes designed for superior flowability, excellent surface area contact, and non-caking performance. The flakes dissolve quickly and completely in aqueous environments through a strongly exothermic reaction, releasing thermal energy that speeds up batch mixing cycles and efficiently creates high-potency alkaline solutions without leaving unreacted solids.

• Heavy-Duty Commercial Packaging: Enclosed in a heavy-duty, reinforced 25kg outer polypropylene woven sack equipped with an internal high-density polyethylene (PE) protective lining. This specialized multi-layer barrier guards against atmospheric humidity, ambient moisture ingress, and carbonation, while providing robust tear and puncture resistance during forklift handling, palletized storage, and long-distance ocean transport.

Primary Industrial Applications

• Commercial Soap & Detergent Production: Functions as an essential strong alkali reagent for mass-producing saponified liquid and solid soaps, commercial surface cleaners, and high-performance anionic surfactants. It ensures precise stoichiometric ratios when hydrolyzing natural fats, tallow, and vegetable oils into smooth, high-quality cleaning products.

• Water Treatment & Environmental pH Control: Widely deployed across municipal water facilities and industrial wastewater plants to rapidly neutralize acidic effluent streams, maintain distribution network alkalinity, control pipe corrosion, and induce heavy metal ion precipitation prior to safe environmental discharge.

• Heavy-Duty Chemical Cleaning & Maintenance: Acts as a fast-acting caustic agent that hydrolyzes fats, breaks down tough proteinaceous soils, and rapidly dissolves heavy grease, organic buildup, and stubborn blockages in industrial pipe networks, commercial drain lines, and automated Clean-in-Place (CIP) systems.

• Pulp, Paper & Textile Processing Operations: Serves as a primary chemical reagent in Kraft pulping processes for dissolving wood lignin to isolate clean cellulose fibers. In textile manufacturing, it is extensively used for raw fiber scouring, bleaching sequences, and cotton mercerization under mechanical tension to enhance fiber tensile strength, dye uptake, and surface luster.

Safety & Handling Protocol

Sodium hydroxide is a highly corrosive Hazard Class 8 chemical capable of causing severe skin burns, permanent eye damage, and tissue destruction upon contact. Personnel handling bulk bags must strictly wear appropriate Personal Protective Equipment (PPE), including splash-proof goggles, full-face shields, heavy-duty nitrile or neoprene gloves, chemical-resistant rubber aprons, and steel-toe protective boots.

Critical Safety Requirement: Always add sodium hydroxide flakes to water slowly with continuous stirring—never pour water directly onto caustic soda flakes. Adding water to solid sodium hydroxide can trigger violent, localized boiling, rapid thermal expansion, and dangerous exothermic splashing of corrosive liquid. Always execute mixing procedures in well-ventilated areas using heat-resistant, alkali-compatible containers (such as high-density polyethylene or stainless steel) while avoiding contact with reactive metals including aluminum, zinc, brass, or tin.
