Product Description
Caustic Soda Flakes, chemically known as Sodium Hydroxide (NaOH), are white solid alkaline flakes with a high melting point and strong corrosive properties. Supplied by Zenco Systems Ltd, these flakes are essential for water treatment, detergents, textiles, pulp & paper, and chemical manufacturing industries across East Africa. They provide efficient pH regulation, neutralization, and surfactant formulation capabilities. The flakes are highly soluble in water, stable under dry storage, and require proper handling with safety measures due to their corrosiveness.
