Compare with Newtonian fluid. A fluid whose viscosity changes when the gradient in flow speed changes. Colloidal suspensions and polymer solutions like ketchup and starch/water paste are non-Newtonian fluids.

A non-Newtonian fluid is a fluid whose flow properties differ in any way from those of Newtonian fluids. Most commonly, the viscosity (the measure of a fluid`s ability to resist gradual deformation by shear or tensile stresses) of non-Newtonian fluids is dependent on shear rate or shear rate history. Some non-Newtonian fluids with shear-independe....

<chemistry, physics> A fluid in which the viscosity varies depending upon the shear stress. The effect can arise because of alignment of nonspherical molecules as flow is established or because of suspended deformable particles as in blood. ... It relates to a fluid in which flow and rate of shear are not always proportional to the applied st...

fluid, such as a grease or a polymer-containing oil (e.g., multi-grade oil), in which shear stress is not proportional to shear rate.
