Applied Rheology for Understanding Flow Instabilities in Polymer Processing
Original language description
Due to the fact that polymer melts behaves as non-Newtonian viscoelastic fluids, their flow behavior is rather complex and leads to number of flow phenomena which have negative impact on their processing and final product properties. The polymer melt elasticity, high shear viscosity, extensional viscosity and its tendency to slip at the solid surfaces causes the flow destabilization. Typical flow instabilities occurring during polymer melt flows are die drool, neck-in, film blowing instabilities and interfacial instabilities in coextrusion. In this work, it is demonstrated how the polymer melt rheology and modeling of polymer processing can be used to understand and minimize the above mentioned flow instabilities occuring in extrusion and coextrusion technologies.
