The Influence of Polymer Rheology on Extrusion Die Design


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.

Why attend?

Polymer rheology is critical for extruder flow channel design since it determines how the polymer will distribute through a die and the pressure requirements for the process. This webinar will discuss how flow channel and die design can be optimized based on the rheological characteristics of the polymer.

Who should attend?

Anyone responsible for or interested in the design, performance or optimization of extruders or extrusion dies.

What will you learn?

About the key rheological characteristics that need to be considered when choosing or designing a flow channel or die for a particular extrusion process and sample type.
