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 discuss the advantages of the Kinexus + series for your rheological measurement. Focus of the talk will be on the practical measurement results at low shears, how the unprecedented gap/axial capabilities of Kinexus can give you ne...
Malvern Instruments has introduced two new models to its Kinexus line of rotational rheometers. The new Kinexus pro+ and Kinexus ultra+ incorporate enhancements to Malvern’s unique proprietary air bearing technology, the performance defin...
Drilling fluids (sometimes called muds) are materials used extensively in the oil extraction industry. Here we look at both aqueous and non-aqueous muds and the measurement of particle size and rheological properties of these fascinating mixtures.
For a coating or ink, particle size, zeta potential and rheology are all important characteristics. All three parameters interact to define the performance of a suspension; understanding these interactions is the key to control of stability
This presentation will highlight the importance of 4 fundamental characterization parameters (size, shape, rheology, zeta potential) to the formulation and specification of coatings, paints, and pigments.
Keeping you in suspense!
