Sodium Hydroxide, also known as Caustic Soda or NaOH, is a widely used inorganic chemical with strong alkaline properties. It is an important industrial chemical used in water treatment, chemical manufacturing, pulp and paper production, textile processing, alumina refining, soap and detergent manufacturing, and many other industrial applications.

We supply Sodium Hydroxide in different grades and forms, including caustic soda flakes, caustic soda pearls and sodium hydroxide solution, according to customer requirements. Our products are available for bulk export and industrial applications, with professional packaging and international shipping support.

What Is Sodium Hydroxide?

Sodium Hydroxide is a strong alkaline compound with the chemical formula NaOH and CAS Number 1310-73-2. It is commonly known as Caustic Soda.

Sodium Hydroxide is highly soluble in water and releases heat when dissolved. Because of its strong alkalinity and excellent chemical reactivity, it is widely used for pH adjustment, neutralization, chemical processing, cleaning, and manufacturing.

Sodium Hydroxide is available commercially in several forms, with 99% Caustic Soda Flakes and Caustic Soda Pearls being common choices for industrial applications. Liquid Sodium Hydroxide solutions are also widely used in continuous industrial processes.

Sodium Hydroxide Specifications

Typical industrial-grade Sodium Hydroxide specifications include:

Specifications may vary depending on the product grade and customer requirements. A detailed COA, TDS and SDS can be provided for specific products and orders.

Sodium Hydroxide 99%

Sodium Hydroxide 99% is one of the most commonly traded forms of Caustic Soda for industrial applications.

99% Sodium Hydroxide is normally supplied as white flakes or pearls. It offers high alkalinity and strong chemical reactivity, making it suitable for applications requiring effective neutralization, pH adjustment and chemical processing.

Our Sodium Hydroxide 99% can be supplied in bulk quantities for international customers, subject to product specifications, packaging requirements and destination regulations.

Caustic Soda Flakes

Caustic Soda Flakes are a solid form of Sodium Hydroxide commonly used in industrial manufacturing and chemical processing.

Caustic Soda Flakes are easy to package, transport and store when handled according to appropriate safety requirements. They are commonly used in:

• Water and wastewater treatment

• Chemical manufacturing

• Pulp and paper production

• Textile processing

• Soap and detergent production

• Alumina and aluminum production

• Petroleum and refinery processes

• Mining and mineral processing

• Industrial cleaning

We can supply Caustic Soda Flakes in bulk with standard or customized packaging according to customer requirements.

Caustic Soda Pearls

Caustic Soda Pearls, also called Sodium Hydroxide Pearls, are another solid form of NaOH.

Compared with flakes, pearls have a granular appearance and can be convenient for certain industrial dosing and handling applications.

Caustic Soda Pearls are widely used in chemical processing, water treatment, detergent manufacturing, textile processing and other industrial applications.

Sodium Hydroxide Solution

Sodium Hydroxide is also available as a liquid solution in different concentrations.

50% Sodium Hydroxide Solution, commonly referred to as liquid Caustic Soda, is widely used in industrial processes where liquid dosing is preferred.

Liquid Sodium Hydroxide can be used for:

• pH adjustment

• Acid neutralization

• Wastewater treatment

• Chemical manufacturing

• Industrial cleaning

• Pulp and paper processing

• Textile processing

• Petroleum and chemical processing

The concentration and transportation requirements should be confirmed according to the customer's application and destination.

Sodium Hydroxide Applications

Sodium Hydroxide is one of the most important basic chemicals used across a wide range of industries.

Water and Wastewater Treatment

Sodium Hydroxide is widely used for pH adjustment and acid neutralization in water and wastewater treatment systems.

It can help increase the pH of acidic wastewater and create suitable conditions for various treatment processes. Caustic Soda is also used in industrial wastewater treatment and chemical precipitation processes.

Chemical Manufacturing

Sodium Hydroxide is an important raw material and processing chemical in the production of various inorganic and organic chemicals.

Its strong alkaline properties make it useful for neutralization, hydrolysis and chemical processing.

Pulp and Paper Industry

Caustic Soda is widely used in pulp and paper manufacturing, including pulping, chemical processing and treatment of wood materials.

Textile Industry

Sodium Hydroxide is used in textile processing, including cotton treatment, mercerization and other processes requiring strong alkaline conditions.

Soap and Detergent Manufacturing

Sodium Hydroxide is an important raw material in traditional soap manufacturing. It reacts with fats and oils during the saponification process to produce soap.

Alumina and Aluminum Production

Caustic Soda is used in the Bayer process for alumina production. It helps dissolve aluminum-bearing minerals and is therefore an important chemical in the aluminum industry.

Petroleum and Refining

Sodium Hydroxide can be used in petroleum refining and other processes for neutralization and removal of certain acidic components.

Mining and Mineral Processing

Caustic Soda is used in selected mining and mineral processing applications where strong alkaline conditions are required.
