About Caustic Soda Flakes

Caustic Soda is a versatile basic chemical with a wide range of industrial applications. It is highly soluble is water and is practically insoluble in most organic solvents exceptalcohols. It is available in the from of lye (solution in water), as solid and as flakes.

Usage

Used in the refining of alumina containing ore like bauxite to produce aluminum oxide
It is a component of drilling mud and is used to increase viscosity
It is used in paper industries for making paper
Used for the manufacture of biodiesel
Used as a catalyst for the trans esterification of methanol and triglycerides
Used with water as paint stripper on wooden objects
It is used to neutralize acids
It is a source of sodium ions for reactions that produce other sodium compounds
When Caustic Soda is reacted with cellulose, it produces rayon and cellophane
Pharmaceuticals
Used for water treatment

Versatile Industrial Applications

Caustic Soda Flakes serve a crucial role across multiple industries, including soap manufacturing, textile processing, pulp and paper production, water treatment, and chemical synthesis. Their strong alkaline properties enable efficient cleaning, degreasing, and pH regulation, making them vital for industrial operations.

Safe and Reliable Packaging

These flakes are securely packed in 25 kg HDPE bags with an inner liner, minimizing moisture absorption and promoting safe handling and storage. The packaging can be customized based on specific requirements and ensures the product remains intact and effective during transit and storage.

Stable and Long-Lasting

When stored in tightly closed containers in a cool, dry, and ventilated environment, caustic soda flakes remain stable, non-perishable, and effective indefinitely. The low moisture and iron content further preserve product quality, meeting the most robust industry standards.

FAQs of Caustic Soda Flakes:

Q: What is the primary chemical composition of caustic soda flakes?

A: Caustic soda flakes are composed mainly of sodium hydroxide (NaOH) with a purity of at least 99%, classified as a strong inorganic alkali.

Q: How should caustic soda flakes be stored to maintain their shelf life?

A: Store caustic soda flakes in tightly closed containers, placed in a dry, cool, and well-ventilated area. Avoid exposure to moisture and keep the packaging intact to ensure indefinite shelf life.

Q: Where are caustic soda flakes commonly used?

A: These flakes find extensive use in the paper, soap, textile, detergent, water treatment, and chemical manufacturing industries, owing to their strong alkaline action and solubility.

Q: What safety precautions should be followed when handling caustic soda flakes?

A: As caustic soda flakes are classified as corrosive (Hazard Class 8), always wear appropriate protective equipment such as gloves and goggles, and avoid skin or eye contact during handling or processing.

Q: How are caustic soda flakes beneficial in industrial processes?

A: Their high solubility and strong alkalinity make caustic soda flakes effective for pH adjustment, cleaning, degreasing, and chemical synthesis, enhancing productivity and process efficiency.

Q: Is there an expiry date for caustic soda flakes?

A: Caustic soda flakes are non-perishable and do not expire if stored correctly in dry, sealed conditions, preserving their stability and effectiveness.
