Caustic Soda Flakes (Sodium Hydroxide Flakes – NaOH)

Caustic Soda Flakes, also known as Sodium Hydroxide Flakes (NaOH), is a highly alkaline and corrosive industrial chemical widely used in various manufacturing and processing industries. Due to its high purity (98–99%), strong reactivity, and fast solubility, caustic soda flakes play a critical role in many industrial applications worldwide.

Caustic soda is commonly supplied in solid white flakes, which offer easier handling, safer storage, and more efficient transportation compared to liquid forms.

How Caustic Soda Flakes Are Produced

Caustic soda flakes are produced through the chlor-alkali process, one of the most important industrial chemical processes.

In this method:

• A purified sodium chloride (NaCl) solution is electrolyzed.

• The electrolysis produces sodium hydroxide (NaOH), along with chlorine gas (Cl₂) and hydrogen gas (H₂) as by-products.

• The sodium hydroxide is initially obtained as a liquid.

• The liquid is then concentrated, cooled, and solidified into flake form for commercial and industrial use.

This production method ensures high purity and consistent quality, making caustic soda flakes suitable for demanding industrial processes.

Applications of Caustic Soda Flakes

Caustic soda flakes are widely used across multiple industries due to their strong alkaline properties:

Soap & Detergent Industry

• Essential for soap manufacturing and saponification processes

• Used in household and industrial cleaning products

Water & Wastewater Treatment

• pH adjustment and neutralization of acidic water

• Removal of heavy metals and impurities

Pulp & Paper Industry

• Delignification and pulping processes

• Bleaching and fiber treatment

Textile Industry

• Fabric preparation, dyeing, and finishing

• Mercerization of cotton fibers

Oil, Gas & Petrochemical Industry

• Refining processes

• Removal of acidic compounds and impurities

Metal & Aluminum Processing

• Bauxite processing in alumina production

• Surface cleaning and treatment of metals

Packaging, Storage & Safety

Caustic soda flakes are typically supplied in 25 kg bags, suitable for bulk handling and export.
As a corrosive and hazardous chemical, strict safety measures must be followed during handling, storage, and transportation. Proper protective equipment and compliant packaging are essential.
