Calcium Carbonate - Calcium Carbonate is a naturally occurring mineral primarily composed of calcium carbonate, processed to achieve high purity, controlled particle size, and consistent chemical properties. It is one of the most widely used industrial minerals due to its versatility, chemical stability, whiteness, and cost-effectiveness. Calcium Carbonate is extensively used as a filler, extender, and functional additive across plastics, paints, paper, rubber, construction, and chemical industries.

Applications
Plastics & Polymers - Used as a functional filler to improve stiffness, impact strength, dimensional stability, and cost efficiency in plastic compounds.
Paints & Coatings - Acts as an extender pigment, improving opacity, brightness, surface smoothness, and rheological properties.
Paper Industry - Used as a filler and coating pigment to enhance brightness, opacity, and printability of paper products.
Rubber Industry - Improves tensile strength, abrasion resistance, and processing characteristics in rubber formulations.

Granular activated carbon is defined as the activated carbon being retained on a 50-mesh sieve. GAC products are made from coconut shell, coal, lignite, and anthracite products. Adsorption is the primary mechanism by which GAC works and the primary reason it is widely used to reduce undesirable taste, odor and color and to improve the safety of drinking water. Coconut granular activated carbon is mainly used for gold recovery. And 4*8mesh coconut shell activated carbon is usually applied for some heavy metals removal from the waste gas. According to different applications, clients can choose different activated carbon types according to the specific working conditions.
