Hema viscosity
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.

WebFigure 3 indicates the variation of viscosity of the C-PUA resin with the content of the HEMA diluent. It can be seen that the pure C-PUA resin showed a viscosity value of 8360 mPa s at 25 °C. ... 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.
