RHEOLOGICAL PROPERTIES AND NUMERICAL SIMULATION OF S-PVC FORMULATIONS IN EXTRUSION DIES

摘要

We report effects of formulation and sample preparations on measured rheological properties relevant for constitutive modelling of die flow in PVC extrusion. Numerical simulations are performed in order to separate non-isothermal and viscoelastic effects in the extrusion experiments as well as self-consistency between constitutive models and measurements.
