Calplex 1

Characteristics
Calplex 1 is an extremely fine and white calcium carbonate filler characterised by a high chemical purity. Due to extremely fine granulation, right granulation distribution of particles and high level of whiteness it is used as a filler in paper industry as well as in the production of paints and lacquers.
