This book is intended to fill a gap between the theoretical studies and the practical experience of the processor in the extrusion of thermoplastic polymers. The former have provided a basis for numerical design of extruders and their components, but generally give scant attention to the practical performance, especially to the conflict between production rate and product quality. In practice extruders are frequently purchased to perform a range of duties; even so, the operator may have to use a machine designed for another purpose and not necessarily suitable for the polymer, process or...

Experts in rheology and polymer processing present up-to-date, fundamental and applied information on the rheological properties of polymers, in particular those relevant to processing, contributing to the physical understanding and the mathematical modelling of polymer processing sequences.
Basic concepts of non-Newtonian fluid mechanics, micro-rheological modelling and constitutive modelling are reviewed, and rheological measurements are described. Topics with practical relevance are debated, such as linear viscoelasticity, converging and diverging flows, and the rheology of...

Thoroughly updated since the publication of the first edition, with new chapters on die design for operators, solids conveying and melting and twin-screw extruders, this book bridges the gap between theoretical studies and the practical experience of the processor in the extrusion of thermoplastic polymers and rubbers. Theoretical discussions generally give little attention to practical considerations, such as the conflict between productivity and product quality. Here however the authors give a clear representation of the physical mechanisms on which so much of the polymer processing...
