Heavy calcium carbonate is a widely existing mineral in nature. It is produced by physically crushing high-purity limestone and possesses excellent whiteness, stability and economy. It is widely used in industries such as plastics, papermaking and coatings. In the future, it will develop towards a more refined and functional direction.

Heavyweight calcium carbonate (GCC) optimizes the structure of paper, enhancing the smoothness of touch, dimensional stability and durability, making writing smooth, printing clear, and the paper supple and flexible. It meets all-round needs ranging from household paper to packaging materials.

This article comprehensively analyzes the core differences between heavy calcium carbonate and light calcium carbonate from the aspects of production process, physical properties to application scenarios, and elaborates on the key role of heavy calcium carbonate in industries such as papermaking and plastics, helping users quickly establish an understanding.
