Introduction to Rheology & Rheological Testing

Workshop Focus on Rheology

Rheology is the study of flow and deformation of materials under applied forces which is routinely measured using a rheometer. The measurement of rheological properties is applicable to all materials from fluids such as dilute solutions of polymers and surfactants through to concentrated protein formulations, to semi-solids such as pastes and creams, to molten or solid polymers as well as asphalt. 

Rheological properties impact at all stages of material use across multiple industries – from formulation development and stability to processing and product performance. The type of rheometer required for measuring these properties is often dependent on the relevant shear rates and timescales as well as sample size and viscosity

The workshop will cover the basic principles and tips and tricks required for successful rheological testing including viscoelastic and Non-NewtonianA non-Newtonian fluid is one that exhibits a viscosity that varies as a function of the applied shear rate or shear stress.non-Newtonian behavior, selection of instrumentation, geometry, test parameters and data analysis. All live demonstration of a NETZSCH rheometer will be used to show the above-mentioned theoretical principles in practice.
