Understanding Rheology of Thermoplastic Polymers
www.tainstruments.comor capillary rheometers, process flows are usually mixed flows with elongation deformations being important and dominant in processes like film blowing, blow molding, fiber spinning, etc. The elongation viscosity of elastic materials at large deformations can deviate significantly from the shear
Viscosity - Saylor Academy
resources.saylor.orgViscosity is measured with various types of viscometers and rheometers. A rheometer is used for those fluids which cannot be defined by a single value of viscosity and therefore require more parameters to be set and measured than is the case for a viscometer. Close temperature control of the fluid is essential to accurate measurements ...

Rheological Techniques for Yield Stress Analysis
www.tainstruments.comrheometers. Since the measurements are mostly done in the linear viscoelastic region of the material, the wall slippage problem is minimized, especially when crosshatched, serrated or sandblasted test fixtures are used. In general the dynamic strain/stress sweep shows excellent reproducibility. Figure 8: Yield stress analysis of blue ink
