Product Description
Caustic soda flakes, chemically known as sodium hydroxide (NaOH), are white opaque solid flakes widely used as a strong alkaline agent in various industrial applications. These flakes dissolve readily in water producing a strongly alkaline solution with a typical pH of 14 in aqueous solutions. Zenco Chemicals supplies high-quality caustic soda flakes suitable for water treatment, pulp and paper production, detergent manufacturing, chemical synthesis, and industrial cleaning. It is essential to handle with proper protective equipment due to its corrosive nature and store in a cool, dry, and ventilated environment to maintain stability.
