Product Description
Calcium Carbonate (CaCO3) is a white crystalline powder widely used as an industrial filler, pH regulator, and alkalinity source. It is insoluble in water but soluble in acids, making it essential in water treatment, manufacturing of plastics, paints, rubber, paper, and as a food-grade calcium supplement. Zenco Chemicals supplies Calcium Carbonate with consistent quality across East Africa including Kenya, Uganda, Tanzania and Rwanda, offering reliable supply chains, bulk packaging options, and technical support for various industries.
