Effect of Extensional Viscosity, Elasticity and Die Exit Stress State on Neck-in Phenomenon during Extrusion Film Casting: Theoretical Study
Original language description
In this work, viscoelastic, isothermal extrusion film casting modeling utilizing 1D membrane model and modified Leonov model was performed in order to understand the role of extensional viscosity, elasticity and viscoelastic stress state at the die exit, on the polymer melt film stretching in the post die area. Experimental data for LDPE and theoretical predictions based on the eXtended Pom-Pom (XPP) model taken from the open literature were used for the validation purposes.
