The Mineralogical and physio-chemical properties of any Calcium Carbonate and Dolomite plays a vital role in its use with any specific polymer.

In the production of plastic compounds, mineral fillers are one of the additives that when incorporated in their formulation defines the quality of the final product.

The effect that fillers produce over the properties of the plastics, is highly dependent on the particle size, the distribution of the particle size, and the strength of the union between the filler particle and the polymeric matrix. In filter’s selection, many properties have to be taken in consideration like:
