Hema viscosity
WebJul 28, 2024 · The critical shear rate was highest with the [St]: [HEMA] = 4:1 formulation and decreased with lower proportions of HEMA. Also, as the HEMA content increases, the initial viscosity decreases. These results imply that ST depends on the proportions of surface-bound PHEMA. WebViscosity is a measure of a filler's resistance to flow when shear stress is applied. As higher amounts of stress are applied, the viscosity of a filler decreases. The shear stress applied from overlying tissue when the filler is in the skin is low enough that the viscosity level does not allow the filler to flow.
