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 this webinar we will show how to measure and apply rheological material functions which are relevant to polymer fabrication and processing. We will address the four general categories of requirements for manufacturing the thousands of products pro...
This live online demo is designed to provide you with a virtual hands-on introduction to the Kinexus rheometer. In this webinar, you will be able to take a look at the Kinexus rheometer and some of its typical measurement systems (geometries) and acc...
Chocolate is an affordable yet luxurious treat with mature markets in Europe and North America and developing markets around the world. The secret of chocolate’s almost universal appeal is in the mouthfeel – the “snap” of the first bite, how the choc...
Thixotropy is associated with reversible, microstructural and time dependent changes that come about due to local spatial rearrangement of microstructural components in a structured fluid.
This frequently found time-response of a microstructure th...
Two smoothie makers have been evaluated and compared by measuring the particle (fiber) size and viscosity of two different smoothies recipes to see which smoothie maker gave the smoothest blend.
