Two types of rubber extrusion analyses from a capillary rheometer (Monsanto Processability Tester) were conducted and calculated results were compared with the experimental data to verify the applicability of these analyses. Analyses were conducted under the condition of two-dimensional axisymmetric incompressible viscous flow. One of the analyses used in this paper is unsteady finite element analysis using marker particles and the other is steady finite element analysis with the streamline integration method. The material model used in both analyses is the power-law model. Calculation results of the unsteady analysis using marker particles were in good agreement with the experimental ones even at high flow velocity. Calculation results of the steady analysis with streamline integration method were poor at high flow velocity. From the calculated results, it was found that it is not always sufficient to use the power-law model for the quantitative analysis of the rubber dieswell from MPT.
