Dolomite mineral filler
Dolomite mineral filler is a double calcium and magnesium carbonate often used in the manufacture of polymer matrix composites, paint industry, agriculture and other productive sectors. AITANA CHEMICALS offers one of whitest and purest dolomites in the world. Rigorous quality control of our mineral fillers allows us to offer our customers maximum guarantees. In the case of dolomite, granulometry and humidity are the key aspects to control. Read on if you want to know more on the advantages and characteristics of our dolomite mineral fillers and how they can affect the quality of the final product.
Characteristics of a high quality dolomite mineral filler
In order to determine the quality of a dolomite, we must take into account the following factors:
-
- a correct granulometry tailored to the specific needs of our final product and the production process. The milling / crushing process and the subsequent classification of the dolomite mineral filler in the factory must guarantee the correct granulometry.
- the purity of dolomite. It is very frequent the presence of impurities, mainly iron and manganese. That is the reason why we should analyze this aspect and select the most appropriate dolomite to our formulation or / and needs.
- its whiteness. For certain types of products, the color of dolomite is a highly coveted element.
- strict humidity control
Dolomite applications
The uses of dolomite mineral filler depend fundamentally on its physical and chemical properties. Depending on these properties we can use this mineral filler in:
-
- polymer matrix composites, as polymer concrete or in applications such as countertops, shower trays, sinks, plates, etc.
- paint manufacturing
- as a mineral filler for ceramic glazes
- adhesive plastic materials manufacturing
- as a mineral filler for rubber
- fertilisers in agriculture. It constitutes a source of magnesium and calcium that allows modifying the ph of the soil. Dolomite mineral manages to regulate the acidity of the soil and thus, improves and increases the profitability of the crops.
- steel industry
- glass industry
