Abstract

The contributions of shear and elongation to the measured pressure drop in flow of polypropylene melts through semi-hyperboloidal dies have been investigated with and without external lubrication. This was done with a set of dies having a fixed ratio of inlet area to outlet area and three different lengths. The flow curves obtained without lubrication have been analyzed for the dependence on length. Two distinct terms have been identified that represent the shear contributions to the measured pressure drop in unlubricated flow.
