Rheological properties like linear viscoelasiticity, temperature dependence, shear rate dependence of viscosity and extensional viscosity are closely related to processability of polymer processing. In this article, relationship between rheological properties of polymer melt and their flow behavior in polymer processing devices especially for film and sheet extrusion, pipe and profile extrusion and calendaring are discussed.
