Calcium Carbonate is one of the essential ingredients taken into use in the paper industry. It is used as fillers and for coating purpose in the industry. The working qualities of CaCO3 like opacity, brightness, and smoothness make it an ideal component for the manufacturing of writing, printing and packaging grade paper. It is mineral filler which substantially reduces the production cost of paper production. As the minerals are easier to get dried than fibers it also reduces the cost of basic materials. CaCO3 is also used in paper coating as it brings brightness and smoothness on the surface of printing paper.
We offer this chemical in several particle size depending upon its usage.
