Calcium carbonate, as an inorganic mineral with abundant natural reserves and excellent cost performance, has become one of the most widely used inorganic fillers in the plastics industry. This is due to its low cost, high whiteness, good chemical stability, and strong mechanical compatibility with polymer materials. It can effectively reduce production costs while improving […]

Among the family of inorganic powder materials, calcium carbonate (CaCO₃) is undoubtedly a shining star. Composed of calcium, carbon, and oxygen, it is widely found in nature in the form of limestone, marble, and calcite. At the same time, it can also be produced on a large scale through industrial synthesis. Thanks to its abundant

Calcium carbonate has become one of the most widely used inorganic fillers in plastic film production. This is mainly due to its low cost, high whiteness, and balanced overall properties. When processed into filler masterbatch for film production, calcium carbonate helps simplify manufacturing processes. It also improves compounding efficiency and increases productivity. In addition, dust

In industries such as plastics, coatings, rubber, papermaking, and artificial marble, calcium carbonate is one of the most widely used and cost-effective functional fillers. In recent years, however, a more advanced and high-performance material—porcelain-white composite calcium carbonate—has been rapidly gaining popularity among customers. So what makes it stand out among so many filler materials? This

Natural calcium carbonate (NCC) is a commonly used abrasive in toothpaste. Typical commercial grades include 325 mesh (D97 ≈ 45 μm) and 400 mesh (D97 ≈ 38 μm). In recent years, toothpaste formulation technology has advanced rapidly. Ultrafine grinding processes have also made significant progress. As a result, finer natural calcium carbonate abrasives are becoming

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

When it comes to industrial fillers, one material is almost everywhere — from PVC pipes and phone cases to latex paint and even calcium supplements in bread.That material is calcium carbonate (CaCO₃). As an abundant, low-cost, and stable performer, calcium carbonate is the “all-rounder” of the materials world. It not only reduces cost but also

In the history of the plastics industry, calcium carbonate has long been regarded as a low-cost filler, valued mainly for reducing raw material costs. However, with breakthroughs in processing technology and the evolution of application demands, this traditional perception is being completely redefined. Today, calcium carbonate has transformed into a functional modifier that combines three

According to different production methods, calcium carbonate can be classified into ground calcium carbonate (GCC), precipitated calcium carbonate (PCC), colloidal calcium carbonate, and crystalline calcium carbonate. Among these, GCC is produced through direct mechanical grinding. Ultra-fine calcium carbonate is an essential non-metallic mineral raw material, widely used due to its abundance, low cost, and performance-enhancing

In the vast world of chemical raw materials, there is a seemingly ordinary yet highly powerful material that is quietly transforming the manufacturing processes and product performance of multiple industries. This material is modified calcium carbonate. After surface activation treatment, modified calcium carbonate is no longer just a simple filler but has become a key
