Workshop, Perth: Introduction to Rheology & Rheological Testing

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-Newtonian behavior, selection of instrumentation, geometry, test parameters and data analysis. A live demonstration of a NETZSCH rheometer will be used to show the above-mentioned theoretical principles in practice.

All attendees will receive an individual copy of the NETZSCH Rotational Rheology handbook (see below). 

Refreshments will be provided throughout the day.
