Hezhen white ultra fine calcium carbonate powder for construction materials rubber industry plastic products environmental materials

Calcium carbonate powder (CaCO₃) is a versatile inorganic compound sourced from natural minerals like limestone, chalk, and marble, as well as the skeletal remains of marine organisms. Production methods include mining—where raw materials are crushed, ground, and classified—and synthetic synthesis, such as precipitating calcium hydroxide with carbon dioxide to create PCC (precipitated calcium carbonate), allowing precise control over particle size and shape.

Valued for its chemical stability and mechanical properties, it serves as a key component in cement to enhance strength, a filler in paper for opacity, and a reinforcing agent in plastics/rubber. Food-grade variants function as calcium supplements or antacids. With its non-toxic nature, abundance, and eco-friendly profile, calcium carbonate powder remains indispensable in construction, manufacturing, and healthcare, driving sustainable industrial innovation.

Product Description

The paper industry benefits from ultrafine heavy calcium powder by improving paper brightness, opacity, and printability, resulting in high-quality, super white paper products. Its fine particle size ensures even distribution, enhancing the paper's physical properties without compromising its aesthetic appeal.

In plastics and PVC manufacturing, this calcium carbonate variant acts as a cost-effective reinforcing agent, improving mechanical strength and dimensional stability while reducing material costs. Its compatibility with polymers facilitates the production of lightweight, durable products with enhanced performance characteristics.

Overall, ultrafine heavy calcium powder exemplifies how precision and purity in raw materials can drive innovation and efficiency across diverse industrial applications.
