Caustic soda / caustic soda granule

Sodium Hydroxide Granules — NaOH Granules

What Is Sodium Hydroxide

Sodium hydroxide is a strong alkali widely used as a chemical raw material and process reagent. The names “sodium hydroxide”, “caustic soda”, “lye” and “caustic” refer to NaOH. For this product, the key distinguishing features are the granular form and a NaOH mass fraction.

Key Characteristics:

Applications

Granular sodium hydroxide is used in chemical and industrial processes, for alkalinity and pH adjustment, in the manufacture of cleaning agents, for cleaning and degreasing, in water treatment and wastewater treatment, and in other processes where sodium hydroxide is specified by the technology. The required working-solution concentration and method of use depend on the specific process.

Dissolving in Water

Granular sodium hydroxide readily dissolves in water. Dissolution releases a significant amount of heat, so heat generation must be taken into account when preparing solutions. Appropriate equipment and safety procedures must be used.

Other Forms of Sodium Hydroxide

This product page is for sodium hydroxide granules. If another form is required, Novohim also offers caustic soda flakes and liquid sodium hydroxide 47%. A detailed comparison of the different forms will be provided in a separate Knowledge Center article.

Storage

Sodium hydroxide must be protected from moisture and exposure to air. Store the product in tightly closed packaging in a dry, enclosed area in accordance with the applicable product documentation.

Limitations and Material Compatibility

Sodium hydroxide is a strong alkali and should not be considered universally compatible with all materials. For tanks, piping, pumps, seals, and other equipment, material resistance to sodium hydroxide must be evaluated for the specific concentration and temperature.

Safety

Sodium hydroxide is a corrosive alkaline substance. Contact with the product or concentrated solutions can cause severe skin burns and eye damage. Appropriate personal protective equipment must be used, and the current safety documentation must be followed.

Frequently Asked Questions

Are sodium hydroxide and caustic soda the same substance?
Yes. Caustic soda is a common name for sodium hydroxide (NaOH). This product page is for the granular form.
Can granular NaOH be dissolved in water?
Yes, but dissolution releases a significant amount of heat, which must be taken into account when preparing the solution.
What is the packaging?
25 kg bag.
Are other forms of sodium hydroxide available?
Yes. Novohim also offers caustic soda flakes and liquid sodium hydroxide 47%.
Buy Sodium Hydroxide Granules
Novohim offers sodium hydroxide granules (NaOH) in 25 kg bags. If another form of NaOH is required for the process, caustic soda flakes or liquid sodium hydroxide 47% can be selected.
