Caustic Soda Flake
New Products From This Supplier
Caustic Soda Flakes, chemically known as Sodium Hydroxide (NaOH), are solid white flakes with a purity of typically 99% minimum. They are highly alkaline, odorless, and hygroscopic, making them ideal for a wide range of industrial applications. When dissolved in water, they generate considerable heat and form a strongly caustic solution.
Manufactured under strict quality controls, our caustic soda flakes are free from heavy metals and impurities, ensuring consistent performance in critical processes. This product is widely used in pulp and paper, textile, soap and detergent production, water treatment, petroleum refining, and chemical manufacturing.
Packaged securely in moisture-resistant bags or drums, our caustic soda flakes offer excellent shelf life and stability during storage and transport.
