Understanding the flow behavior of polymer melts is the basis of die design. Cloeren is equipped with a state-of-the-art rheology laboratory and can characterize the viscoelastic properties of polymer melts in shear and extensional flows. We will work with your materials on new projects, as well as evaluate materials for your existing Cloeren equipment. Our team can help you with material selection for complex coextrusion scenarios.
The interpretation of the viscoelastic data is as important as obtaining the data itself. Over the years, our experts have developed in-house non-Newtonian and temperature dependent viscosity models that can fit most complex behaviors and be used in subsequent flow simulations.
