Purpose & Overview
This is an intensive introduction to the science and technology of multilayer co-extrusion. The seminar covers the reasons for using co-extrusion as compared to alternative technologies for producing multipolymer combinations. The methods used in selecting polymers for co-extruded product designs are examined, and polymer properties for sealant layers, barrier layers and combining incompatible materials are reviewed. Equipment selection, design considerations and material flow properties are reviewed in depth to ensure the design of robust co-extrusion systems. Methods to characterize existing equipment and materials will be reviewed to allow the determination of process ranges and effective troubleshooting of co-extrusion instabilities and defects. Equipment design principles are covered to permit better vender interaction in equipment selection, design and process control.

Who Should Attend?
Process and product development scientists and manufacturing engineers needing an intensive introduction, or review, of co-extrusion principles for effective process design, specification, control and troubleshooting.
