Uniaxial Extensional Experiments with Large Strains Performed with Low Density Polyethylene (LDPE)

  • T. Raible
  • J. Meissner


In this paper results of three different types of extensional experiments are presented, which were performed with a new version of the Uniaxial Extensional Rheometer with rotary clamps: (A) extension with constant strain rate, (B) recovery after cessation of extension with constant strain rate, and (C) extension with constant tensile force. The LDPE used had a density at 20°C of p20 = 0.919 g/ cm3 and a melt flow index of MFI =1.37 g/10 min /1/. The test temperature was 150°C.
