Polymer Processing (EBT 322/3)

Building on the extraordinary success of six best-selling editions, Bill Callister's new Seventh Edition of MATERIALS SCIENCE AND ENGINEERING: AN INTRODUCTION continues to promote student understanding of the three primary types of materials (metals, ceramics, and polymers) and composites, as well as the relationships that exist between the structural elements of materials and their properties.

Co-authored by Kenneth G. Budinski and Michael K. Budinski, his son, with over 50 years of combined industry experience in the field, this practical, understandable introduction to engineering materials theory and industry-standard selection practices provides readers with the working knowledge to (1) make an informed selection of materials for engineering applications and (2) correctly specify materials on drawings and purchasing documents. Encompassing all significant material systems—metals, ceramics, plastics, and composites—this text incorporates the most up-to-date information on material usage and availability, addresses the increasingly global nature of the field, and reflects the suggestions of numerous adopters of previous editions.Within the four major material categories, this edition includes specific coverage of international metal buying, plastic families, “survivor” ceramics, and composite coatings. Other topics include surface engineering; tribology (friction, wear and lubrication); material properties; cemented carbides; steel making; heat treating; and corrosion—including a treatment of electrochemistry.Appropriate for all materials engineers.

Polymer Processing: Principles and Design presents the background required to design processes for thermoplastics. Often engineers are hired by the polymer industry to develop and design processes for thermoplastics, to design polymer processing machinery, to develop processes for new polymers, and to optimize existing processes. However, at best, they receive only a little training in polymer science and no training in the design of polymer processes. This book emphasizes the fundamental concepts that allow the student and the practicing engineer to carry out practical design decisions. While most books leave the student with equations only, Polymer Processing: Principles and Design provides the numerical methods required to solve the equations using the personal computer and easy-to-use IMSL numerical subroutines, and ensures a solid foundation in the principles underlying the design of polymer processing techniques.

This widely acclaimed text, now in its fifth edition and translated into many languages, continues to present a clear, simple and concise introduction to chemical thermodynamics. An examination of equilibrium in the everyday world of mechanical objects provides the starting point for an accessible account of the factors that determine equilibrium in chemical systems. This straightforward approach leads students to a thorough understanding of the basic principles of thermodynamics, which are then applied to a wide range of physico-chemical systems. The book also discusses the problems of non-ideal solutions and the concept of activity, and provides an introduction to the molecular basis of thermodynamics. Over five editions, the views of teachers of the subject and their students have been incorporated. The result is a little more rigour in specifying the dimensions within logarithmic expressions, the addition of more worked examples and the inclusion of a simple treatment of the molecular basis of thermodynamics. Students on courses in thermodynamics will continue to find this popular book an excellent introductory text.

Modern polymer processing can no longer be regarded as a mere shape conversion operation; rather, it is a route to the achievement of specific properties in a given system, involving substantial reorganization at the nano and molecular levels. Our understanding of the mechanisms governing the development of structure in the different routes by which polymeric raw materials are transformed into useful artifacts is a very important subject, keystone in the control and enhancement of plastic products. This book presents a compilation of recent studies in the area, presenting a comprehensive, tutorial review of the interrelationships between the properties, structure and processing of polymeric materials. Readership: Postgraduate level, interested in structure and morphology of polymeric systems, modern characterisation techniques, crystallisation mechanisms and kinetics, structure-property relationships, and structure development in various processing techniques.

Polymer Processing Instabilities: Control and Understanding offers a practical understanding of the various flows that occur during the processing of polymer melts. The book pays particular attention to flow instabilities that affect the rate of production and the methods used to prevent and eliminate flow instabilities in order to increase production rates and enhance manufacturing efficiency. Polymer Processing Instabilities: Control and Understanding summarizes experimental observations of flow instabilities that occur in numerous processing operations such as extrusion, injection molding, fiber spinning, film casting, and film blowing for a wide range of materials, including most commodity polymers that are processed as melts at temperatures above their melting point or as concentrated solutions at lower temperatures. The book first presents the fundamental principles in rheology and flow instabilities. It relates the operating conditions with flow curves, the critical wall shear stress for the onset of the instabilities, and new visualization techniques with numerical modeling and molecular structure. It reviews one-dimensional phenomenological relaxation/oscillation models describing the experimental pressure and flow rate oscillations, analyzes the gross melt fracture (GMF) instability, and examines how traditional and non-traditional processing aids eliminate melt fracture and improve polymer processability. It supplies a numerical approach for the investigation of the linear viscoelastic stability behavior of simplified injection molding flows and examines a newly discovered family of instabilities that occur in co-extrusion. Polymer Processing Instabilities: Control and Understanding is unique in that it fills a gap in the polymer processing literature where polymer flow instabilities are not treated in-depth in any book. It summarizes state-of-the-art developments in the field, particularly those of the last ten years, and contains significant data based on this research.

Based on lecture notes from a five-week polymer processing laboratory course taught at the University of Wisconsin-Madison, this text provides background on polymer processing for engineering students and practicing engineers.

Plastics processing is a major industrial activity, which yields components and systems for a wide range of industries, such as packaging, automotive, aeronautics, electrical and electronic, sports and leisure, toys, civil and construction, and agriculture. Most plastic components are manufactured either by extrusion or injection moulding, but other techniques such as blow moulding and thermoforming are also important. The productivity of these technologies is dictated by the equipment design, choice of the operating conditions and physical properties of the polymer system. This book discusses the recent scientific developments on the optimisation of manufacturing engineering problems and applies them to polymer processing technologies.
