During the mixing process, fillers are added to the rubber with the aim of improving the mechanical properties of the end product. Since fillers are present as agglomerates, they must be broken up during the mixing process (dispersion), as otherwise they will lead to defects in the compound and thus to a reduced end product performance. The aim of the project is to select a suitable formulation and the associated processing conditions. To achieve this goal, it is essential to consider the dispersion.
