Extrusion is by far the most important and the oldest processing and shaping method for thermoplastic polymers. This process concerns almost all synthetic polymers, as well as elastomers or food materials. Single-screw extrusion is mainly used nowadays to manufacture finished goods or semi-finished products. More than 90 million tons of thermoplastics are therefore processed every year. Twin-screw extrusion may be divided into two systems: contra-rotating systems used within the context of PVC extrusion, for the manufacture of pipes or profiles; and co-rotating systems experiencing nowadays a very significant development, because of their significant adaptability and flexibility, which enables the manufacture of specific materials (polymer alloys, thermoplastic elastomers, filled polymers, nanocomposites). Extrusion is carried out by passing molten polymer through a tool called die that will give the product its final shape (films and sheets, rolled products, and electric cables). Thanks to the design of dies, we obtain at the output a product with controlled dimensions, uniform speeds and homogeneous temperatures. The book will discuss the same production types, but only in the case of coextrusion flows, i.e. multilayer stratified products. First of all, we will present in this book the physics of the mechanisms at stake, then propose more or less complex models in order to describe these mechanisms and then go forward in the interpretation of results and the control of condition flows.

The author presents single-screw extrusion technology together with the relevant polymer fundamentals, with an emphasis on screw design. The presentation begins on a physical level, providing an in-depth conceptual understanding, followed by an analytical level with mathematical models. Practical applications of the mathematical models are illustrated by numerous examples. A brief description of twin-screw extrusion technology is also presented. New in the third edition: a novel patented barrier screw design that eliminates shortcomings of all previous barrier screw designs, more descriptive specific screw design guidelines, a scientifically designed pineapple mixing section, and general improvements and corrections. Contents: • Physical Description of Single-Screw Extrusion • Fundamentals of Polymers and Melt Rheology • Theories of Single-Screw Extrusion and Scale-Up • Screw Design and High Performance Screws • Gear Pumps, Static Mixers, and Dynamic Mixers • Die Design • Viscoelastic Effects in Melt Flow • Special Single-Screw Extruder with Channeled Barrel • Physical Description of Twin-Screw Extruders

The second edition of Extrusion is designed to aid operators, engineers, and managers in extrusion processing in quickly answering practical day-to-day questions. The first part of the book provides the fundamental principles, for operators and engineers, of polymeric materials extrusion processing in single and twin screw extruders. The next section covers advanced topics including troubleshooting, auxiliary equipment, and coextrusion for operators, engineers, and managers. The final part provides applications case studies in key areas for engineers such as compounding, blown film, extrusion blow molding, coating, foam, and reprocessing. This practical guide to extrusion brings together both equipment and materials processing aspects. It covers basic and advanced topics, for reference and training, in thermoplastics processing in the extruder. Detailed reference data are provided on such important operating conditions as temperatures, start-up procedures, shear rates, pressure drops, and safety. A practical guide to the selection, design and optimization of extrusion processes and equipment Designed to improve production efficiency and product quality Focuses on practical fault analysis and troubleshooting techniques

The extrusion die is one of the most critical elements of an extrusion system. However, very few books have been devoted exclusively to die design. This book will combine a thorough engineering approach to die design with a practical, hands-on approach. The authors together have over sixty years of experience in extrusion and die design. They have been involved in all aspects of die design: polymer rheology, analysis of flow, layout of extrusion dies, testing of new extrusion dies, troubleshooting die related problems, maintenance of extrusion dies, etc.
