What is Caustic Soda Flakes?

Caustic Soda Flakes, also known as sodium hydroxide (NaOH), is a common and essential chemical raw material. Unlike liquid and granular forms of sodium hydroxide, caustic soda flakes appear as white, opaque thin flakes, characterized by high purity and efficiency. These flakes are highly pure, easy to store and transport, dissolve quickly in water, and are stable. These advantages make caustic soda flakes widely used in various fields such as chemical production, paper manufacturing, textiles, water treatment, and petroleum refining. For instance, they are used as a crucial base chemical in industries like fertilizers, synthetic fibers, dyes, and pharmaceuticals. In the paper industry, they are used for pulp production and processing. In the textile industry, they are employed for bleaching and dyeing textiles. In water treatment, they are used to adjust pH levels and purify water. In petroleum refining, they are used for deacidification and purification. Overall, due to their high efficiency, ease of use, and stability, caustic soda flakes have become an indispensable chemical in various industries.

Our Caustic Soda Flakes have a purity of 98% sodium hydroxide (NaOH), ensuring high effectiveness and reliability for various industrial applications such as chemical manufacturing, water treatment, and textile processing.

Caustic Soda Flakes should be stored in a cool, dry, and well-ventilated area, away from moisture and incompatible materials such as acids. Ensure the container is tightly sealed when not in use.

While Caustic Soda Flakes are effective in various applications, they are highly caustic and should be handled with proper protective equipment, including gloves, goggles, and protective clothing, to prevent skin and eye contact.

Caustic Soda Flakes dissolve more rapidly than other forms like pearls or solid blocks, providing a controlled and uniform dissolution rate. This makes them particularly suitable for precise applications and reduces dust during handling.
