Sodium Hydroxide (Caustic Soda Flakes)

Sodium hydroxide, with the chemical formula NaOH, is commonly known as caustic soda, lye, or sodium hydrate. It is a strong alkaline inorganic compound that exists as a white flake, pellet, or bead-shaped solid at room temperature.Sodium hydroxide is often transported and used in the form of Sodium Hydroxide Flakes.

It is highly hygroscopic, readily absorbs moisture and carbon dioxide from the air, and dissolves in water with a strongly exothermic reaction. Sodium hydroxide is one of the most widely used industrial chemicals globally, with applications spanning paper making, textiles, food processing, petroleum refining, water treatment, and chemical manufacturing.

Sodium Hydroxide Flakes (also known as caustic soda flakes) is a highly corrosive and strong alkaline inorganic compound widely used in industrial processing. It is a fundamental raw material in multiple downstream industries including textiles, paper, petroleum refining, and water treatment.

Product Overview

Sodium hydroxide (NaOH), commonly referred to as caustic soda or lye, is one of the most fundamental industrial chemicals produced worldwide. It is a strong base with excellent solvation and saponification properties. In its solid form (flakes, pearls, or pellets), it is easy to handle, store, and dose for industrial use.

The product is available in multiple purity grades — most commonly 98% and 99% — to meet the requirements of diverse industries including pulp and paper, textiles, food processing, pharmaceuticals, and water treatment. Caustic soda is classified as a corrosive substance and requires appropriate handling precautions including the use of gloves, goggles, and protective clothing. Our production facility operates under ISO 9001 quality management to ensure consistent product quality batch after batch.
