The paint industry uses dry granulated calcite with a size of 1, 3, 5, 20, 40 microns. The most demanded product group is calcite of 5 microns. The calcite is added in 25-35% proportion to water-based construction paints used in interior and exterior coating.

An important part of this is calcite produced for use in filling and 25-30% of it is coated calcite. In Europe, watery granulated calcite, usually 60% below 2 microns, is used for filling purposes in the paper industry with 75% water and 25% solid. Moreover, 88-90% is used for the coating of watery granulated coated calcite, less than 2 microns.

Calcium carbonate provides good optical properties to graphic paper and is relatively inexpensive. Therefore, the use of calcium carbonate for the production of paper has steadily increased.

Paper Industry. One of the biggest clients for calcium carbonate Powder supplier is the paper sector. When producing paper, calcium carbonate is mostly utilised as a filler. A significant amount of calcium carbonate is added to the paper to ensure its tensile strength and whiteness while also cutting production costs.

The increasing demand for plastic and paper packaging is anticipated to be the main factor driving the growth of the calcite industry. This has produced an anticipated amount of US$ 20.22 billion by 2033, with a CAGR of 5.9% from 2023 to 2033. The paper sector has seen a huge increase in demand for calcite.
