Flow curve in order to determine the plateau value of the vis­cosity performing a shear rate controlled flow curve at low enough shear rates in steady state.. The standard tests for measuring the Zero ...

The traditional method for determining yield stress on a rotational rheometer or viscometer was by fitting models to the measured rheograms and extrapolating to zero shear rate. This article discusses ...

Rheological testing of thermoplastic materials can be carried out on both melts and solid samples. Issues related to process ability can be correlated with polymer melt properties, or problems ...
