Product Description
Calcium carbonate exists as a white, odorless and tasteless solid. Based on distinct crystal structures, it falls into categories such as the calcite type, aragonite type, and vaterite type. It shows insolubility in both water and alcohol. However, when it comes into contact with dilute acids, a chemical reaction occurs, resulting in the liberation of carbon dioxide gas.

Application
During papermaking, the addition of calcium carbonate serves multiple purposes. Firstly, it enhances the opacity and whiteness of the paper, while also improving its smoothness, which in turn significantly boosts the printability. This ultimately leads to better writing and printing results on the paper. Secondly, it helps in cutting down the production cost of paper. Additionally, it strengthens the physical properties of the paper, for example, it increases the tensile strength and folding resistance of the paper, making the paper more durable and suitable for various applications.
Calcium carbonate finds extensive application in the rubber industry. It has the ability to augment the volume of rubber, thereby enabling a reduction in the production cost of rubber products. Moreover, it plays a crucial role in enhancing the processing characteristics of rubber. For instance, it promotes more efficient mixing within the rubber, effectively decreasing the viscosity of the rubber compound. As a result, this makes the formation and processing of rubber products much more convenient and straightforward.
When calcium carbonate is used as a filler in plastics, it offers two main advantages. Firstly, it cuts down the production cost of plastics. Secondly, it enhances the properties of plastics. It boosts the rigidity, hardness, and dimensional stability of plastics. This means that during the usage of plastic products, the shrinkage and deformation are reduced. Due to these benefits, calcium carbonate is extensively utilized in manufacturing a wide range of plastic products, including those made from polyethylene and polypropylene.
