Viscoelastic

Some fluids exhibit both viscous and elastic properties. These liquids are then not only resistant to motion, but will also, with the cessation of the movement, want to return back to their original state. These viscoelastic fluids form a problem for mixing processes. ‘Dead zones’ can easily occur and such fluids exhibit the tendency to creep upwards along the agitator shaft. Examples of viscoelastic fluids are elastomers and adhesives. Examples of viscoelastic fluids are elastomers, polymers and glues.
