Calcium Carbonate (Uncoated)
Calcium Carbonate (uncoated) is a naturally occurring mineral compound composed primarily of calcium, carbon, and oxygen with the chemical formula CaCO₃. It appears as a fine white powder or granules, widely used as a filler, pigment, and functional additive across various industries. The uncoated form means the calcium carbonate particles are not surface-treated, retaining their natural properties. It is valued for its high brightness, whiteness, and excellent compressibility. Uncoated calcium carbonate is used to enhance opacity, improve processing, and reduce costs in plastics, paints, coatings, adhesives, rubber, paper, and construction materials.
Calcium Carbonate Light
Calcium Carbonate Light is a finely ground, low bulk density natural mineral composed primarily of calcium carbonate (CaCO₃). Compared to standard grades, it has a lower density and larger particle size distribution, making it suitable for applications where light weight and high brightness are important. This form is extensively used as a filler and extender in industries such as plastics, paints, rubber, paper, adhesives, and construction materials to improve opacity, brightness, and texture, while maintaining low weight and cost efficiency. Its chemical inertness and whiteness provide functional and aesthetic advantages across formulations.
