is to force polymers to flow through dies and process equipment. During single-screw extrusion, shear rates may reach 200 s–1 in the screw channel near the barrel wall, and much higher between the flight tips and the barrel. At the lip of the die the shear rate can be as high as 1000 s–1. Low shear rate on a die wall implies slow movement of the polymer melt over the metal surface. Some
