The Influence of Polymer Rheology on Extrusion Die Design
The polymer rheology, in relation to the flow channel design, determines how a polymer will distribute through a die and what pressure is required to be generated by the extruder. The webinar will describe the most important rheological characteristics that must be considered and how they affect the design of the flow channels or the flow distribution through a given die. The relationship between polymer rheology and the die’s ability to be "self cleaning", and avoid degradation, will also be discussed. The presentation will also provide design strategies that can help minimize the potential for degradation, and make dies less sensitive to rheological characteristics that can vary from lot-to-lot, in order to make the performance more stable and trouble free.
