Product Overview
About Caustic Soda Flakes
Caustic soda flakes, chemically known as sodium hydroxide (NaOH), are a strong inorganic alkali widely used in industrial manufacturing. These white, crystalline flakes dissolve rapidly in water, producing a highly alkaline solution capable of neutralizing acids, breaking down organic materials, and facilitating chemical reactions.
As one of the most essential base chemicals globally, sodium hydroxide flakes are manufactured and supplied in bulk to support high-demand industries across North America.

Manufacturing Process
How Caustic Soda Flakes Are Made
The production of sodium hydroxide flakes involves several controlled industrial steps:
- 1.
Membrane Cell Process
High-purity sodium chloride (brine) undergoes electrolysis using advanced membrane cell technology.
This produces sodium hydroxide solution along with chlorine and hydrogen as co-products. Modern membrane technology ensures low impurity levels and energy efficiency.
- 2.
Evaporation
The resulting sodium hydroxide solution is concentrated through multi-stage evaporation to achieve the desired strength.
- 3.
Flaking Process
The concentrated liquid is cooled and solidified into thin flakes using specialized flaking equipment. This ensures uniform size, easy handling, and rapid solubility.
- 4.
Quality Control
Each batch undergoes strict quality testing to maintain 98–99% purity, low heavy metal content, and consistent composition.
All production processes adhere to global manufacturing standards suitable for regulatory and industrial compliance requirements across North America.
