Description

Sodium Hydroxide is a fundamental inorganic compound and a cornerstone industrial chemical. Its powerful alkaline properties make it an essential reagent and processing agent across a vast range of manufacturing sectors. Key industries that rely on this product include chemical manufacturing, pulp & paper production, water treatment, textiles, and food processing. We supply high-purity grades to meet the stringent demands of global industrial and specialty chemical applications.

Application

• Chemical Manufacturing: A key raw material for producing sodium salts, soaps, detergents, and organic chemicals like dyes and pharmaceuticals.
• Pulp & Paper Industry: Critical in the kraft process for digesting wood pulp and in bleaching operations.
• Water Treatment: Used for pH adjustment, water softening, and regeneration of ion-exchange resins.
• Alumina Production: Essential in the Bayer process for refining bauxite to produce alumina (aluminum oxide).
• Food Processing: Employed for chemical peeling of fruits and vegetables, cocoa processing, and as a cleaning agent for food processing equipment (food grade).
• Textile Processing: Used in mercerizing cotton to increase its strength, luster, and affinity for dyes.
• Biodiesel Production: Acts as a catalyst in the transesterification of vegetable oils or animal fats.
• Cleaning & Degreasing: A powerful component in industrial and domestic drain cleaners and degreasers.

Storage

Preserve in a tightly closed container, protected from light. This product is highly hygroscopic (moisture-sensitive) and must be stored in a cool, dry, well-ventilated area away from incompatible materials such as strong acids and organic solvents. Store at room temperature (15-25°C). Ensure containers are kept tightly sealed to prevent absorption of atmospheric moisture and carbon dioxide.
