DUCALCIT – The importance of calcium carbonate in various industrial sectors, with a special emphasis on its use as a filler in the polyvinyl chloride (PVC) industry. Among all fillers used in PVC processing, 80% are calcium carbonate-based. Fillers are used to improve various mechanical properties of polymers such as tensile and breaking strength, density, hardness, thermal stability, viscosity, and more. The latest trends in industrial development, as well as the demands of the processing industry for higher-quality carbonate fillers, have led to the introduction of surface modification processes for limestone (calcite)—the main component of finely micronized limestone—in order to enhance its properties. DUCALEN is an eco-friendly masterbatch – a filler in granule form with a high content of selected ultra-fine natural calcium carbonate blended into an LLDPE carrier with a slip agent. DUCALEN is mainly intended as an additive for film-blowing extrusion, and is also used in injection molding, thermoforming, pipe extrusion, and similar technologies.DUCALEN increases productivity and reduces extrusion pressure, improves dimensional stability, shortens cooling time and cycle duration in the injection molding process, enhances mechanical properties, and lowers the cost of the final product.
