A New Look at Extensional Rheology of Low-Density Polyethylene

The nonlinear rheology of three selected commercial low-density polyethylenes (LDPE) is measured in uniaxial extensional flow. The measurements are performed using three different devices including an extensional viscosity fixture (EVF), a homemade filament stretching rheometer (DTU-FSR) and a commercial filament stretching rheometer (VADER-1000).

Characterizing Long-chain Branching in Commercial HDPE Samples via Linear Viscoelasticity and Extensional Rheology

Abstract It is well established that polymer chain architecture and the distribution of molecular weight play a key
