When added to plastics and rubber compounds, industrial minerals do improve specific properties of the polymer like tensile strength and toughness. By doing so, the properties of the polymer are improved. Therefore the industrial mineral has to be chemically the purest and has to remain stable during and after blending into the polymer matrix for a longer period of time not causing any ageing effects in the final polymer-based product. The main industrial mineral used worldwide is natural ground calcium carbonate(GCC). A whole bunch of product families of calcium carbonate is available to match every customer requirement.
Concrete applications ranging from very simple to highly sophisticated concrete can be optimized by using a grade from the product group ALPHAMENT®. ALPHAMENT® is micronized calcium carbonate based on natural, very pure reef lime, which was formed millenniums ago. ALPHAMENT® from each production location shows a constant natural shade of grey.
Calcium carbonates of the product family CALCICARB® are produced at the plant Kainach in Austria based on color-selected white marble rocks. CALCICARB® is mainly used in the construction industry in all cases where the surface of the construction product is not visible. CALCILIT® products of similar fineness are preferred for visible white or bright colored construction products.
Adhesives and sealants are often designed to show ‚natural warm‘ colors. In such applications CALCICARB® is a very good choice allowing to create exactly this effect due to its stable natural whiteness.
For sure there is a quite big financial benefit in all kind of applications when using CALCICARB® instead of a high-white filler in combination with a color pigment.
Calcium carbonates of the product family CALCILIT® are products made from bright white marble rock of extreme chemical purity.
For the cast industry, CALCILIT® granules in qualities of 0,5 mm gradings are available which have an extremely narrow particle size distribution curve.
For applications in the paint, lacquer and plastics industry all the standard finenesses down to finest particle-sized CALCILIT® products with average diameters lower than 1µm are available.
For polymer applications, CALCIPLAST® products are bright white calcium carbonates being surface-modified, which leads to processing advantages and allows higher loadings in many polymer-based applications.
Several new products CALCIPLAST® HS have been designed to show 100% hydrophobic behaviour. This allows to venture into market niches that have been barred for surface-modified products until now.
For paper industry, calcium carbonates of the product family CALCICELL® combine high whiteness with chemical purity. Further product advantages are low abrasivity as well as the availability of any fineness below 2 microns the customer might desire. Available are qualities to be used as filler as well as finest qualities as coating colour pigments.
The product family CALCIFIN® comprises fine naturally white calcium carbonates of German origin, based on Jurassic rock. CALCIFIN® leads to ‚warm natural‘ colors in the final product and is used already in a lot of new developments of state-of-the-art sustainable products of our daily life.
Initially conceived as one of the first industrially manufactured industrial minerals, at that point-in-time named ‚fillers‘, the product family CALCICOLL® meanwhile stands for calcium carbonate qualities based on Jurassic rock which are used as basic white industrial mineral in a lot of applications like latex, adhesives, construction chemistry and so on.
Calcium carbonates of the product family CALCITUFT® are products in the shade segment ‚natural light grey‘. For decades, their main application area is in floor coverings. Nowadays, a couple of ‚natural shades of grey‘ is created in different final products by using such ‚natural light grey‘ calcium carbonates.
Originally, the ‚natural light grey‘ product family FOAMCARB® has been conceived for the foam layer in the carpet industry. In the meantime, FOAMCARB® products have also established themselves in many other application areas to create natural shades of grey.
Originally developed for flooring, but in the meantime used in all kinds of applications, CALCIFILL® offers naturally light grey lime stones having a top cut of about 200 micron. Several CALCIFILL® products are already certified as recycling products, others will follow within short.
First certified sustainable range of natural calcium carbonate in Europe, based on 100% recycled natural white marble rock. As a multifunctional filler base, it reduces product costs, increases product performance and sustainably improves rheological properties.
