Film blowing process stability analysis for non-newtonian fluids by using variational principles

Abstract

In this work, the stability analysis has been performed for the film blowing process by using variational principles for non-Newtonian polymer melts. Specific attention has been paid to the investigation of the complicated links between polymer melt rheology (extensional strain hardening/thinning), molecular structure (Mw - molecular weight, LCB - long chain branching) and film blowing stability.
