Fig. 5.7 (a) Relative mixture viscosity (mixture viscosity divided by pure binder viscosity) versus the solids loading. (b) Mixture density versus the solids loading. At the critical solids loading, the viscosity increases rapidly as the density passes through a maximum. More

Fig. 8.4 Temperature dependence of viscosity for several glasses. The “working range” is the temperature range in which glasses can be economically shaped. The straight lines on the semi-log plot do not extend below the glass transition temperature. More

Figure 28 Spin on ARC coating. The RPM and viscosity of the liquid define the film thickness and therefor the desired index match. Typically a gold to light blue color film gives optimum results for NIR work. More

Fig. 3.10 Feedstock viscosity at room temperature for an alumina (Al 2 O 3 ) tape casting formulation, demonstrating viscosity reduction with the addition of a phosphate ester. Source: Moreno ( Ref 1 ) More

Fig. 3.22 Viscosity versus shear strain rate for high-density polyethylene at temperatures of 170, 190, and 210 °C (340, 375, and 410 °F). Shear thinning is evident by the reduction in viscosity as the strain rate increases, and thermal softening is evident by the temperature effect. More

Fig. 3.24 Test data for the viscosity of polypropylene at 200 °C (390 °F). The linear decrease in viscosity with higher shear strain rates is the basis for extracting a sensitivity exponent M = −0.63. More
