Heavy calcium carbonate, produced via physical processing, offers distinct advantages over light calcium carbonate: lower production costs, significantly reduced oil absorption, and a more pronounced boost to the surface gloss of end products. As a result, it has become the preferred filler for the vast majority of manufacturers.
Its applications span key industries including rubber, plastics, papermaking, and coatings. Beyond these, it also sees extensive use in pharmaceuticals, food processing, feed production, and toothpaste manufacturing.
