Investigating the Effect of Rheological Parameter Ratios on the Mixing Properties of TPU Blends

Abstract

Front Cover: The rheological parameters are important factors influencing mixing of polymer blends. The tracer particle method is used to represent the mixing effect of the melt, the flow of virtual material/thermoplastic polyurethanes with high and low viscosities in dynamic mixers are simulated. The patterns of zero shear viscosity ratio, relaxation time ratio and non-Newtonian index ratio influencing the mixing are discovered.
