Extensional Rheology in Polymer Processing

Extensional Rheology in Polymer Processing Extensional flows dominate many polymer processes, including blow molding, film blowing, fiber spinning, thermoforming and many others. The rheology of polymeric materials under extensional flows can differ significantly from shear flows and it is important to understand this in order to optimize both materials and processes. In this webinar, we…

An Introduction to Tribo-Rheometry: Quantifying Friction

An Introduction to Tribo-Rheometry: Quantifying Friction Tribology complements rheology, providing information on solid-solid interactions that adds insight to the bulk fluid measurements of rheology. Tribology is especially concerned with quantifying the coefficient of friction as a function of sliding speed and load force, under dry or lubricated conditions. This provides useful information about lubrication, wear,…
