The substitution of established materials in conventional product groups (as in construction) as well as the development of new applications for new materials is becoming increasingly significant with regard to the ecological and economical requirements. investigations on high loaded mixtures with a polyolefin-based matrix were carried out with the aim of material development. In order to improve its properties, renewable modifiers were added to the plastics. In order to reduce the number of experiments, mixtures were developed using the method of simplex grid plans (mixture plans). The objective of this method was to determine a function for a property of a compound depending on its composition By creating mathematical models of this type, prior computation can be used to predict the properties of any composition of the compound being investigated.
