Modified Calcium Carbonate Technologies and High-Performance Powder Coating Equipment for Plastics & Rubber

By

Modified calcium carbonate has evolved from a simple filler into an essential functional additive across the plastics and rubber industries. From PVC pipes and PE agricultural films to automotive bumpers and electronic enclosures, surface‑modified, composite‑modified, and nano‑modified calcium carbonate grades deliver precisely tailored performance at a fraction of the cost of virgin polymers. But formulation […]

Calcium Carbonate Surface Modification with a Pin Mill: Process, Parameters, and What the Numbers Mean

By

Unmodified calcium carbonate has a hydrophilic surface. Plastics, rubber, and cable compounds are hydrophobic. Put an unmodified CaCO3 filler into a polymer matrix and the two materials resist each other: poor dispersion, reduced tensile strength, weak interfacial adhesion between filler and matrix. The compound performs worse than unfilled polymer in several critical properties. Surface modification

High-End Calcium Carbonate Powder: Advanced Processing Technologies and Innovative Applications

By

Calcium carbonate (CaCO₃) is one of the most widely used inorganic non-metallic minerals in the world. Abundant, low-cost, chemically stable, and non-toxic, it has served as a functional filler in plastics, papermaking, coatings, rubber, and construction materials for decades. Yet in its ordinary ground form, conventional calcium carbonate has well-known limitations. They’re poor dispersion in

Is Calcium Carbonate Really Flame Retardant? The Role of Inorganic Fillers in Fire-Safe Materials

By

Inorganic particles offer a range of benefits including non-toxicity, excellent dimensional stability, high-temperature resistance, and large specific surface area. These properties help enhance the thermal stability, mechanical performance, and electrical conductivity of flame retardants while reducing water absorption. As a commonly used filler in polymer modification, calcium carbonate has lots of advantages. They include rigidity,

Calcium carbonate (CaCO₃)

The role of calcium carbonate (CaCO₃) in plastic modification

By

Calcium carbonate (CaCO₃) is a common inorganic compound. In nature, calcium carbonate exists in many forms, such as calcite, limestone, marble, etc. It is the main component of many rocks and minerals. From a chemical point of view, calcium carbonate decomposes into calcium oxide (CaO) and carbon dioxide (CO₂) at high temperatures. It can react
