WebThe Mooney viscosity of the sample set was measured by the standard method and the values were in the range 65–95 units. The samples were divided in two subsets, one for calibration, containing 70 samples, and the other for external validation, containing the remaining 30 samples. The Mooney viscosity average values and their standard ... WebFigure 2: High Shear Reduced Viscosities vs. Mooney Viscosities This correlation allows ACOMP to target specific grades, potentially allowing for the real-time tracking of the Mooney viscosity through constant monitoring of the reduced viscosity. Furthermore, the composition of a polymer can be correlated to the reduced viscosity.
