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.

Enhanced Oil Recovery (EOR) is gaining increasing attention due to the need of oil extraction in efficient manners and difficulties in finding a new oil field. With traditional methods, only about 20-40% of oil is extracted from an oil reservoir, lea...
Squeeze flow rheometry involves compressing a material between two parallel plates in order to determine its rheological properties. Squeeze flow measurements can be made with a rotational rheometer having suitable axial capabilities (normal force an...
