Study of coextrusion flows in polymer processsing

The analysis presented here shows how computer simulation can be used as a practical design tool to analyze coextrusion flow fields which typically occur in coextrusion process and improve the design of the equipment. Of course, the design can never be optimum for all structures because practicality dictates that several structures must be produced from one single coextrusion die. In fact because of market changes (and dies typically outlast …
