Calplex products are made of marbled gravel with a crystal rhombohedral structure. Calplex is a group of white calcium carbonate fillers, from extremely fine ones to those with a medium granulation, especially well-known for their high chemical purity, high level of coverage, sufficient specific surface and a low level of oil absorption.
