Rheo-Info for Capillary Rheometer

Capillary rheometer - determination of relaxation behavior

Due to constantly increasing process speeds in plastics and rubber processing, the elastic properties of polymer materials are becoming increasingly important.



Determining operating points in extruders and dies

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.



Corrections of Capillary Rheometer Experiments

Experiments with a high-pressure capillary rheometer are often the only way to determine the viscosity at higher, process-relevant shear rates.



RAM – vs. Screw Extrusion?

Advantages of the discrete, discontinuous RAM extrusion compared to the conventional screw extrusion in the clean room production.
