WebCross-WLF viscosity model has become a powerful solution that describes the shear rate- and temperature-dependent characteristics. To estimate the behavior of polymers in computational simulations, the coefficients of the Cross-WLF model should be well identified. An identification technique was proposed to determine the Cross-WLF viscosity WebMay 4, 2024 · The equation 11 indicates that in the Cross-WLF viscosity model, D 3 is regarded as a constant because K f is thought to be irrelevant with P. But actually it is not true. For example, as shown in the Figure 2, Panlite L-1225L(PC) which is an exhibition of the relationship between the specific volume
