Screw extruders are the workhorses of the plastics industry. They are used to pump, mix, carry out chemical reactions, and devolatilize polymer systems. Screw Extrusion helps to obtain an understanding of the underlying principles of operation for screw extrusion equipment, thus helping the engineer in optimizing equipment and enhancing production rates. Most importantly, the book promotes a concise understanding of the processes governing extrusion, solid conveying, melting and metering. By combining numerous contributions from both industry and academia this book is an invaluable resource for the plastics industry and everyone involved in this field.
