Calcium carbonate (CaCO3) is the most widely used filler in polymer formulations. As a filler, calcium carbonate allows cost reduction and improved mechanical properties. It is found in sedimentary rocks (chalk, limestone), marbles and minerals (dolomite). Some typical properties are: density 2.7-2.9 g/cm 3; pH of water suspension 9; particle ...
