Shear Rate Dependence
Shear rate’ is proportional to the speed or flow rate that a TPE is moving against the wall of the tool.
Due to this unique viscosity/shear rate dependency, normal melt index testing (done at shear rates as low as 50 1/sec) will not reflect how the TPE will process at higher shear rates.
