Main ingredient: Calcium carbonate, chemical formula CaCO₃
 

Features:

Calcium carbonate is an inorganic compound with the chemical formula CaCO?. It is a white fine crystalline powder, tasteless and odorless. It is commonly known as gray stone, limestone, stone powder, etc. Calcium carbonate is alkaline, basically insoluble in water, and soluble in hydrochloric acid. It is one of the common substances on the earth. It is found in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine. It is also the main component of some animal bones or shells. Calcium carbonate is also an important building material and is widely used in industry.

Nano calcium carbonate is also called ultrafine calcium carbonate. The most mature industry for the application of nano calcium carbonate is the plastics industry, where it is mainly used in high-end plastic products, which can improve the rheology of plastic masterbatch and improve its formability. Our company's nano-calcium carbonate is used as a plastic filler to toughen and reinforce the plastic, improve the plastic's flexural strength, flexural elastic modulus, thermal deformation temperature and dimensional stability, and also imparts heat hysteresis to the plastic. At the same time, nanometer calcium carbonate is used in ink products to demonstrate excellent dispersion, transparency, excellent gloss, excellent ink absorption and high drying properties. Our company's nano-calcium carbonate is used as ink filler in resin-based inks. It has the advantages of good stability, high gloss, does not affect the drying performance of printing ink, and strong adaptability.
