Chem Source supplies high purity fine Calcium Carbonate obtained from white and high brightness sources.

Ground limestone is available in a broad range of sizes. When specifying the size of a ground calcium carbonate, either the top size (the size of the largest particles) or the median particle size (essentially the average) can be used.

Ground calcium carbonates can range down in particle size to just a few microns, 1 to 3, with the top size controlled for high performance applications to 5 microns
