Abstract
This paper reports on the results of an integrated study focusing on the extrusion behavior of viscoplastic polymeric suspensions. The rheological behavior including Navier's slip wall condition of a viscoplastic suspension was characterized employing multiple viscometric flows, the pressure and temperature history in co-rotating twin screw extrusion process was simulated using FEM and compared to experimental data collected with a well-instrumented 50.8 mm twin screw extruder. The model results agreed well with experimental data and provide a detailed understanding of the thermo-mechanical history that the polymeric suspension undergoes during twin screw extrusion. The developed methodologies provide processors with valuable tools for investigating the continuous processability of various filled materials.
