WebUnderstanding the rheological (flow) properties of a polymer helps obtain optimized material properties during the molding process. Rheology testing can determine if materials are processed properly with minimal product degradation. Rheological tests to measure the viscosity of a polymer ranging from single point tests to variable shear-rate tests. WebRheology and viscous behavior. Figure 1.1. Rheology is a branch of physics. Rheologists describe the deformation and flow behavior of all kinds of material. The term originates from the Greek word “rhei” meaning “to flow” (Figure 1.1: Bottle from the 19th century bearing the inscription “Tinct (ur) Rhei Vin (um) Darel”.

Rheology is the study of the flow of matter, primarily in a fluid (liquid or gas) state, but also as "soft solids" or solids under conditions in which they respond with plastic flow rather than deforming elastically in response to an applied force. Rheology is a branch of physics, and it is the science that deals with the deformation and flow of materials, both solids and liquids. The term rheology was coined by Eugene C. Bingham, a professor at Lafayette College, in 1920, … WebWe provide instruments for single-point rotational measurements, flow curves, structural analysis in oscillation, and sophisticated material analysis with two drive units in one device.
