Webinar invitation: Making elasticity measurements with rotational rheometers

A rotational rheometer is required to enable a complete understanding of material flow and deformation behaviour for complex viscoelastic materials – from low viscosity polymer and surfactant solutions, through to suspensions and emulsions and high particle-loaded semi-solids such as pastes, and high viscosity polymer melts.

Such material types are commonly encountered across a wide variety of industries from personal care and cosmetics, paints and coatings, foods and polymer products, and it is often the material’s elasticity component that will strongly influence their processing and application behaviour.

Knowing a rheometer can help you solve your processing or product performance issues is the starting point, but knowing what test to run to best suit your sample and evaluate its elasticity can be a challenge. With a rotational rheometer, in principle the elasticity of materials can be measured by making normal stress difference, oscillatory, creep recovery, and stress relaxation measurements. But which test is most appropriate for my sample type?

Here’s where we hope we can help you – if you want to know the best test to measure the elasticity for your materials you need to attend Malvern’s web seminar on May 2, 2013 titled “Making elasticity measurements with rotational rheometers“. It will help you in deciding what tests are most relevant, which is often the biggest challenge. Furthermore, your sample type itself may restrict your choice of measurement, and from experience we have learned some tests are more suitable than others. Information in the literature can be difficult to find as to the shortcomings of certain tests for particular material types, and this seminar aims to address these concerns.

If elasticity measurement is an issue for you – hope you can join us on May 02!
