Numerical study of influence polymers properties on the co-extrusion process

The paper studies process coextrusion of the three-layers insulation coating. The main focus this investigation is the analysis effect rheological and thermophysical characteristics on the process of heat and mass transfer in the forming tool. In this paper consider six sample polyethylene. Model have been implemented by through of the finite volume method in Ansys software package. Dependency graphs for temperature, pressure along the channels lengths and temperature fields have been obtained.
