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 ...

In order to understand the benefits and drawbacks of the melt-flow-rate (MFR) test completely, it is essential to know something about how the test is carried out. The methodology is included in ASTM ...

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 ...
