This seminar offers comprehensive coverage of the extrusion of polymeric materials. It is intended for individuals who have little or no background in the extrusion process or for those who have been using single screw extruders and want to gain a thorough understanding of the interrelationships between the polymeric materials, the equipment and processing variables. Lectures discuss the significant characteristics of polymeric materials and their effect on the extrusion process. Single screw extruders and their components, equipment specifications, instrumentation, and screw geometry are discussed. Operational principles including solids conveying, plastication, mixing and pressure generation of single screw extruders are explained. Specific extrusion processes including blown film, flat film and sheet, tube and pipe, profile, wire and cable coating, extrusion coating, and foam extrusion are discussed and expanded upon if requested by participants. Troubleshooting techniques and operational strategies are covered.
