WebA capillary rheometer is an apparatus designed to measure shear viscosity and other rheological (= flow) properties. Capillary rheometers for plastics are piston-die systems designed to measure viscosity of polymer melts as a function of temperature and rate of deformation. They are capable of testing basic polymers, compounds, various ...

WebNov 4, 2024 · The Basics of Capillary Rheometry. Rheology studies the deformation and flow of fluids. Traditionally, capillary rheometers have been used to measure the shear … Webseries of high-pressure capillary rheometers (HCR). Both the PVT device and the capillary rheometer (PVT add-on) always determine the p-v-t behavior of a polymer melt at rest. In the injection molding process, however, these are dynamic processes, meaning that the material properties change. list of ways to cook an egg

WebThere are basically two types of capillary rheometers: speed-controlled and pressure-controlled. The discussion in this contribution is limited to speed-controlled capillary rheometers in which the flow rate is imposed and the pres-sure is monitored. A schematic of the capillary rheometer is shown in Fig. 1. When measuring shear viscosity with ...
