The goal of this contribution is the validation of a viscoelastic material model, which allows consideration of the interaction of the typical swelling behavior of viscoelastic fluids and the shear rate dependent viscosity of industrial used rubber blends in the context of an extrusion process. With this knowledge more realistic numerical simulations of the die swell phenomenon and its influence on the resulting profile geometry are possible. (© 2008 WILEY‐VCH Verlag GmbH & Co.
