Reviewer 2 Report

The work provided one  model to predict the influence of CO₂ solubilization on the flow (plasticizing effect) and a global model to simulate the extrusion process and foaming inside and outside the die. Generally, the study presented one new method, which would  simplify the foaming process for high levels of CO_{2 .} However, there are bigger error on the model accuracy.  Because the final modelling density is about 410 kg/m³ when the experimental one is about 610 kg/m³ . I suggest that the work should improve the accuracy.
