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 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,…
Rheo-Microscopy: Bridging Rheology, Microstructure & Dynamics The combination of optical microscopy with rheological tests enables direct observation of material structure under shear deformation. This provides critical information that can help understand, predict, and tune the material response under processing, storage, or end-use conditions.
Morphology Of Complex Nanoparticle Mixtures The performance of new materials and devices depend heavily on morphological considerations: degree of crystallinity, conformation of amorphous species, and relative organization of one species with respect to another, characteristics which can be determined by thermal analysis. These considerations are important for functional materials such as photovoltaics and MEMS devices,…
