Flow curves of polymer melts (the graph of viscosity versus shear rate in the log-log scale) has two distinct behavior of Newtonian and Power law. At very low shear rates the Newtonian behavior dominates where the viscosity is independent of the shear rate and it approaches the value of η_0 which has been named as the zero-shear viscosity

A thermal stability test can determine the resistance of a polymer melt to a change in the molecular structure at the test temperatures. The results of this test depend on the temperature, residence time at that temperature, material formulation, presence of moisture and/or contaminates

One of the key factors in any MIM process is the flow behavior of the feedstock during filling of of the mold. In order to have a defect free molding process (without jetting, short shot, sink mark, crack, etc.) with desired mechanical strength (tensile, flexural, failure stress, etc.) in the final products, understanding of the rheological properties of the binder and feedstock is necessary

Capillary rheometers are one of the most common types of analytical devices, used to analyze the flow properties of viscoelastic polymer materials under processing conditions. The Dynisco LCR7001 can utilize both load cell and pressure transducer simultaneously in order to produce information on both the force applied to the polymer sample and the resulting pressure at the die entrance.

It can be very difficult, if not impossible, to achieve complete indentification of most polymer products. However, in most cases, this is usually not needed; what is needed is the separation, or identification, of numerous molding materials whose identity has been lost, or an indication of the type of material used to create a component.
