Calplex 40

Characteristics
Calplex 40 is a filler made of natural calcium carbonate characterised by a high chemical purity. Due to the regular particle dispersion and its whiteness it is used as a filler in the production of plasters and glues as well as in the floor coverings, detergents, gaskets and ceramic industries.
