Thermo-Rheological Investigation and Modeling of the Shear Viscosity of Polypropylene above the Melting Temperature

The increasing use of polymeric materials in the daily life, leads to challenges in the processing industry to deliver high performance materials with affordable terms. However, new processing techniques lead to high costs. In order to reduce processing costs it is necessary to understand the non-Ne...
