Which is More Suitable for Plastics—Light Calcium or Heavy Calcium?

By

Among the many filler and modification materials used in the plastics industry, calcium carbonate holds an irreplaceable position. It is generally divided into heavy calcium carbonate and light calcium carbonate. This raises an important question for plastic formulators:Which is more suitable for plastic products—light calcium or heavy calcium? Understanding the Difference Between Heavy Calcium and […]

How Does a Pin Mill Effectively Disperse Nano-Calcium Carbonate?

By

Nano-calcium carbonate (nano-CaCO₃) is an ultrafine functional filler with a primary particle size typically below 100 nm. It is widely used in plastics, rubber, coatings, inks, and adhesives to improve mechanical strength, opacity, and rheological properties. However, due to its high surface energy and strong van der Waals forces, nano-calcium carbonate tends to agglomerate during

Six Perspectives of Ground Calcium Carbonate

The Six Perspectives: What Do We Need to Know About Ground Calcium Carbonate?

By

1. What Is Ground Calcium Carbonate? Ground calcium carbonate (GCC) is a white powder produced by mechanically grinding natural calcium carbonate minerals such as calcite, limestone, dolomite, chalk, and shells. It typically appears as a gray-white or light brown granular solid with slight acidity, high purity, and stable composition. As a widely used industrial raw
