Ultrafine calcium carbonate (ultrafine/nano calcium carbonate) is a critical industrial filler. It is widely used in modern polymer composites, high-end plastic masterbatches, and the rubber and coatings industries. It provides both toughening and modification effects while reducing production costs, making it an indispensable raw material in these fields. To improve its dispersibility and compatibility within […]

In modern industry, calcium carbonate (CaCO3) has evolved beyond being a mere “extender” used to reduce costs. With the rapid advancement of the polymer materials industry, transforming inexpensive mineral resources into high-value active reinforcing fillers has become a focal point of research in material science. Ultra-fine grinding technology has fundamentally altered the destiny of calcium

As global “plastic bans” gain momentum, biodegradable plastics represented by PLA (Polylactic Acid) and PBAT (Polybutylene adipate terephthalate) have become core materials in fields such as green packaging and ecological agriculture. However, due to challenges like high raw material costs and unstable processing performance, calcium carbonate (CaCO3)—as an abundant, eco-friendly, and low-cost inorganic mineral filler—has

Calcium carbonate is the most widely used and largest-volume inorganic mineral filler. However, its naturally hydrophilic and oleophobic surface characteristics lead to poor compatibility with organic polymer materials such as plastics, rubber, and resins. When added directly, it tends to agglomerate, which seriously affects the processing performance and mechanical properties of downstream products. Surface modification
