There is a strong link between what is called the weight-average molecular weight of a polymer and a parameter called the zero-shear viscosity. Although the correct link rather depends on the polymer, ...

Flow curves of polymer melts (the graph of viscosity versus shear rate in the log-log scale) have two distinct behaviors governed by Newtonian and Power law. The Newtonian behavior dominates at very ...

Packaging of a number of consumer products is done in tubes or bottles wherein product application involves pumping the product through a nozzle. These products are basically shear-thinning products ...
