Rotational rheometry is a powerful technique for the measurement of complex shear rheology across all material types – sensitive enough to measure the viscosity of dilute polymer solutions, and yet robust enough to measure the viscoelasticity of high modulus polymers or composites. Rotational rheometry is ideal for discerning structural and compositional changes of materials, which can be critical controlling factors in flow and deformation properties, and ultimately product stability and performance.
The basics of the rotational rheometry technique are as follows:
Rotational rheometry also enables other rheological properties to be evaluated, including yield stress, thixotropy, creep and recovery and stress relaxation.

In part three of our inkjet ink webinar series we will focus on inkjet ink performance and the importance of rheology for evaluating and controlling printing behavior. The main factors influencing printing behavior are viscosity, elasticity and surfa...
Polymeric materials are the most studied of all rheological materials and polymeric solutions in particular are perhaps the most interesting. They are ubiquitous in every-day life and play an important role in applications ranging from joint lubricat...
This app note shows how a three step shear rate test can be used to evaluate the extent of viscosity recovery following extrusion from a tube or bottle.
This application note shows how the power law model can be used to quantify shear thinning behavior and for comparing between products and formulations.
