Caustic Soda Flakes (Sodium Hydroxide)

Caustic Soda Flakes (Sodium Hydroxide – NaOH) | Industrial Supply and Distribution by ChemTech

Introduction to Caustic Soda (Sodium Hydroxide, NaOH)

Caustic Soda, also known as Sodium Hydroxide (NaOH), is a strong alkali and one of the most important basic chemicals in the industrial sector.
It appears as white solid flakes or crystals and is widely used in chemical processing due to its strong neutralizing, pH-adjusting, and hydrolyzing properties.

ChemTech, as a trusted chemical trading and distribution company, supplies Caustic Soda Flakes in industrial and laboratory grades, sourced from reputable international manufacturers. All products are delivered in standard packaging with guaranteed purity and consistency.

Industrial Applications of Caustic Soda Flakes

Caustic Soda is a highly versatile chemical with applications across a wide range of industries:

1. Pulp and Paper Industry

Used for delignification, bleaching, and improving pulp quality in paper manufacturing.

2. Soap and Detergent Production

Acts as a key raw material in saponification, the process that converts fats and oils into soaps and detergents.

3. Petrochemical and Refining Industry

Used for neutralization of acidic streams, gas scrubbing, and chemical synthesis in refineries and petrochemical plants.

4. Aluminum and Metal Processing

Essential in the Bayer process for alumina extraction and used in degreasing and cleaning of metals.

5. Textile Industry

Applied in fiber treatment, mercerization, and dyeing processes to enhance texture and color absorption.

6. Water and Wastewater Treatment

Used to control pH, neutralize acids, and precipitate impurities in water treatment systems.

7. Food and Pharmaceutical Industry

In certain grades, sodium hydroxide is used as a pH regulator and cleaning agent under controlled conditions.

8. Chemical Manufacturing

Serves as a base reagent in the production of sodium salts, solvents, and various chemical intermediates.

Safety and Handling Information

Caustic Soda (NaOH) is a highly corrosive material, requiring strict safety precautions:

• Personal protection: Use alkali-resistant gloves, safety goggles or face shield, protective clothing, and safety boots.
• Contact with skin or eyes: Rinse immediately with plenty of water for at least 15 minutes and seek medical attention.
• Mixing with water: Always add flakes to water slowly while stirring—never add water to caustic soda. The reaction is exothermic (releases heat).
• Storage: Keep in a cool, dry, well-ventilated area, away from moisture and acids.
• Compatibility: Avoid contact with acids, oxidizing agents, and reactive metals such as aluminum or zinc.
• Transportation: Classified as a corrosive material under ADR/IMDG/IATA transport regulations.
