Calcium Carbonate Strong Color Retention

Calcium carbonate Calcium carbonate fillers have ideal properties for many polymer applications and the world consumption is over ten million tonnes annually. Both natural (ground (natural) calcium carbonates, GCC) and synthetic forms are in use and can be derived from abundant and widely occurring natural deposits. The natural forms are available with a wide particle-size range (0.5 to over 100 m), are less expensive to manufacture, and have the bulk of the market. They are widely used in thermoplastics, thermosets, andelastomers. Their main use is in elastomers and PVC. Fatty acid surface coatings are often added and there are also specialized coupling agents available. Calcium carbonates is a critical and functional mineral for plastics, and there is no doubt that it willcontinue to be one of the principal fillers used by the polymer industry.
