Extensional flows dominate many polymer processes, including blow molding, film blowing, fiber spinning, thermoforming and many others.
presentation will discuss techniques for identifying and minimizing experimental errors and for pushing the experimental limits of rotational shear rheometers. The objective is to enable participants to identify bad shear rheology data.
What is rheology and how can you use it to practically describe the flow and deformation of structured fluids and soft solids? Neil Cunningham will provide an accessible introduction to key rheological behaviours.
Rheology is defined as the science of deformation and flow and in particular refers to materials that show viscoelastic or non-Newtonian behaviour when stressed.
In this guest webinar, Professor Howard Barnes aims to provide a simple understanding of this situation, and highlights how to bring about a more desirable rheology when necessary.
What makes a viscometer a rheometer and which instrument do I really need for my application?
