Due to constantly increasing process speeds in plastics and rubber processing, the elastic properties of polymer materials are becoming increasingly important.
It is vital to know the exact operating point conditions in order to be able to assess the impacts of viscosity differences realistically in the fields of plastics extrusion and injection molding.
Experiments with a high-pressure capillary rheometer are often the only way to determine the viscosity at higher, process-relevant shear rates.
