Extrusion Visualization - from Blend Structure to Sharkskin

Abstract
Over the last five years, we have developed optical technologies for in-line monitoring of extrusion. We review two areas where we have succeeded in uncovering important concepts and phenomena by shedding light on processes that were previously unobservable. In the area of polymer blends, we have made real-time observations of blend microstructure during extrusion. we found conditions by which droplets could align in the vorticity axis. In the area of sharkskin and polyolefin extrusion, we have visualized how polymer process additives act and what causes sharkskin.Proceedings Title
