Understanding Rheology

What is Rheology? Rheology is the study of how a material deforms during and after a force is applied. Rheology directly affects product handling and flow characteristics. Some common measurements used to describe rheology are viscosity, thixotropic index, dispense rate, and sag resistance. Why is Rheology Important? Controlling rheological properties is essential for polymeric processing […]

An Introduction to Rheology and Viscosity

Viscosity is a measure of the resistance of fluid to an applied stress. In everyday terms it is like the “thickness” of a fluid or gas. For example, water has a low viscosity so it appears “thin”. In comparison, honey has a higher viscosity, so it appears “thick”. Viscosity essentially describes a liquids internal resistance […]
