Audited Supplier | The heavy calcium carbonate series products are made of high-quality calcite or ice island stone and are processed by international advanced crushing and grinding technology. They have the characteristics of high whiteness, less impurities, narrow particle size distribution and low oil absorption value. Heavy calcium carbonate appears to have an irregular shape, but it is actually rhombohedral or rhombic. For different application areas, Warner's heavy calcium carbonate products use different surface treatment technologies to obtain good application results. In the rubber, plastics and coatings industry, it can not only fill polymer resins, save costs, but also play a dual role of reinforcing and toughening when the particle size is small enough. In paper filling and coating, Warner's ground calcium carbonate has a very high retention rate, which can improve paper strength and whiteness. |
