+To define a gas-loaded polymer, select the polymer (Material A) and gas or choose the gas from the gas database. Further state the mass contents of polymer and gas and thermal conductivity, Sp. heat capacity and density of the gas if the chosen gas is not listed in the gas database.

+The calculation of all material data except of the viscosity is based on linear mixing rules.

+There is only one option to calculate the viscosity of a gas-loaded polymer in SIGMA. So, the Carreau function is preselected for the viscosity function.
+Carreau:
+$n = \frac{A \cdot a_T \cdot a_{gas}}{(1 + B \cdot a_T \cdot a_{gas} \cdot \dot{\gamma})^C}$
+You can choose from different temperature dependence.
+  * WLF ($T_b, T_s$)
+  * WLF ($C_1, C_2$)
+  * Arrhenius
+These different models for the temperature shift factor a_T are described in detail in subchapter rheological data.
