Bingham Plastics act as a rigid body until a certain force is applied, then it acts as a liquid. Toothpaste is a Bingham Plastic. Pseudo-plastics (shear thinning) decrease in viscosity when more force is applied. Example of pseudo-plastics include: nail polish, WebTypical examples for pseudo-plastic fluids are polymer solutions and similar solutions of high molecular weight substances. At low shear rates, these liquids will experience the formation of shear stress. The shear stress results in the reordering of the molecules in order to reduce the overall stress. fishing alert recorce pack
