Plastics and rubber materials, or polymers, are increasingly the first choice of engineers when reliable, cost-effective performance and safety are essential. The volume of polymers used in the Western economy now exceeds that of metals, which requires today's engineering students to have a thorough grounding in the properties and applications of polymeric materials. The first chapters of Engineering with Polymers explain what polymers are, how they behave, and how articles are made from them. The authors then show how the standard engineering techniques of stress analysis, structures, fluid mechanics, heat transfer and design can be adopted or adapted to cover plastics and rubber materials. The book ends with chapters detailing interactions between processing and properties, and a description of a variety of approaches to designing plastics products, from practical advice to the use or further development of theoretical principles, backed up by examples and case studies. The book is aimed at mechanical engineering students and design engineers in industry and also at materials' and chemical engineers.

Filling a need, this ready reference brings together the hard-to-get and recently acquired knowledge usually only found scattered in the original literature. Following an introduction to plastics as a class of engineering materials and an overview of their properties, the book comprehensively covers the characterization and quality control of manufactured plastic components, including an exhaustive treatment of the possible flaws of plastics inadvertently introduced during manufacturing along with viable solutions to prevent these faults. The second part is concerned with the testing of the resulting end products by various physical and chemical methods on the nano-, meso- and macroscale. An appendix with thermoanalytic data and international standards for the most commonly used polymers in plastics engineering rounds off the text. Written by experienced academics and industrial researchers and developers who intimately know the problems faced by plastics engineers in their daily work - as well as the solutions - this book provides first-hand practical knowledge and in-depth discussions for industrial chemists and materials scientists alike.

This is the second of a two volume series of books about fluoroplastics. Volume 1 covers the non-melt processible homopolymers, requiring non-traditional processing techniques. Volume 2 is devoted to the melt-processible fluoropolymers, their polymerization and fabrication techniques including injection molding, wire, tube, and film extrusion, rotational molding, blow molding, compression molding, and transfer molding. Both a source of data and a reference, the properties, characteristics, applications, safety, disposal, and recycling of melt-processible fluoropolymers are comprehensively detailed for immediate use by today's practicing engineering and scientists in the plastics industry. Students will benefit from the book's arrangement and extensive references.

The overall aim of this book is to aid the process of sourcing and selecting appropriate thermoplastic polymers. There are now a wide diversity of thermoplastics offered for commercial uses. At one end of the range are the high-volume commodity materials for short life consumer applications. Whereas at the other end are the high value engineering materials; with significant levels of mechanical, physical and electrical performance. Within this publication, the generic groups of thermoplastics can be identified, along with their respective attributes and limitations. All thermoplastics are available in different grades. The constituents selected to form a grade are chosen to modify aspects of material behaviour, both during processing and in the final moulded form. The directory addresses materials which can be obtained in granular, powder or paste form for subsequent processing. Information is not provided directly on semi-finished product forms, such as films, fibres, sheet or profiles, other than when inferred from the processing descriptions of specified grades. The directory covers virgin or compounded material. It does not specifically address reclaimed or recycled grades. Data is provided for the mechanical and physical properties of moulded grades as processed by the route intended by the primary manufacturer (M) or compounder (C). Material grades can be obtained from a number of sources; either the original polymer manufacturer or a recognised compounder who produces a range of grades.

This book describes an effective framework for setting the right process parameters and new mold design to reduce the current plastic defects in injection molding. It presents a new approach for the optimization of injection molding process via (i) a new mold runner design which leads to 20 percent reduction in scrap rate, 2.5 percent reduction in manufacturing time, and easier ejection of injected part, (ii) a new mold gate design which leads to less plastic defects; and (iii) the introduction of a number of promising alternatives with high moldability indices. Besides presenting important developments of relevance academic research, the book also includes useful information for people working in the injection molding industry, especially in the green manufacturing field.
