Twin Screw Extrusion : Technology and Principles, 2nd Edition

Twin screw extrusion has become an important part of polymer processing technology. Twin screw extruders are used widely for reactive processing, including both polymerization and grafting reactions, for compounding, blending, devolatilization, as well as for thermoplastic final shaping operations, particularly profile extrusion. Twin screw extruders represent not just one technology but can be categorized as :
• Non-intermeshing counter-rotating
• Intermeshing counter-rotation
• Intermeshing co-rotating.

The purpose of this book is to carefully describes each of these three types of machines and the historical development of their technologies. The book also provides insight into the efforts to model/simulate the flow characteristics of these machines and into the experimental studies of their machine characteristics.

This book is unique in clearly distinguishing between the different types of twin screw extruders on the market and in reviewing their capabilities. It provides a balanced and in-depth overview of twin screw extrusion technology to chemists, engineers, and technologists alike.
