Today engineers, designers, buyers and all those who have to work with plastics face a dilemma. There has been a proliferation of test methods by which plastic properties are measured. The property data measured by these test methods are not identical and sometimes have large differences. How are engineers, designers, buyers going to decide the type and resin grade and their property data? Which are the valid test methods? The right plastic property data are the difference between success and failure of a design, thus making the property selection process critical. For the first time this book provides a simple and efficient approach to a highly complex and time consuming task. There are over 26,000 different grades of polymers and millions of parts and applications, further adding to the difficulty of the selection process. Selection of Polymeric Materials steers engineers and designers onto the right path to selecting the appropriate values for each plastic property. A large amount of property information has been provided to teach and assist the plastic part designer and others in selecting the right resin and properties for an application. Various standards including ASTM, ISO, UL, and British Specifications have been discussed to help the readers in making sound decisions A simple and efficient approach to a highly complex and time consuming task Allows engineers to select from various standards including ASTM, ISO, UL, and British Specification Presents information on properties such as tensile strength, melt temperature, continuous service temperature, moisture exposure, specific gravity and flammability ratings Tried and true values narrow myriad choices down quickly for readers

This book is derived from a recent project sponsored by the Polymer Engineering Directorate of the SERC and carried out at the University of Lancaster under the joint auspices of the Departments of Chemistry and Engineering. The project set out to provide a novel type of teaching material for introducing polymers and their uses to students, especially of engineering. Case studies of real examples of polymers at work are used, so the student or teacher can start with a successful and well-designed product and work backwards to its origins in the market, in design and material selection and in the manufacturing process. The philosophy is that such an approach captures interest right at the start by means of a real example and then retains it because of the relevance of the technical explanation. This after all is what most of us do habitually; we turn to examples to make our point. The hope is that subject matter with a somewhat notorious reputation among engineers, such as aspects of polymer chemistry and the non-linear behaviour of polymers under mechanical loading will be fairly painlessly absorbed through the context of the examples. Each study becomes a separate chapter in the book. The original studies, and hence the present chapters, vary in length because different topics demanded different approaches. No attempt has been made to alter this, or to adopt a standardized format because to have done so would have interfered with the vitality of the original work.

Plastics Product Design Provides the reader with access to lessons learned in the author’s 40 years of plastics product design experience Part 1 of the book provides the reader with an introduction to plastics as a design material and a discussion of materials commonly in use today. There is a discussion of a variety of processes available to the designer to make a part along with the design considerations each process will entail. This section also includes a discussion of useful prototyping processes, including advantages and disadvantages of each. Next, the book discusses general design considerations applicable to most plastics product designs. In Part 2 of the book the author discusses elements of design of a number of generic plastic product types based on his more than 40 years of experience of product design and development for several companies with a variety of products. This section includes discussions of structural components, gears, bearings, hinges, snap fits, packaging, pressure vessels, and optical components. This section also discusses the general considerations that apply to these applications as well as specific insights about each particular application. There is also a chapter on the most important joining techniques. Part 2 ends with a discussion of the general design process. The book concludes with 3 appendices on thermal properties of selected generic materials; properties of selected structural components; and common abbreviations for plastic materials. Audience This book is aimed at product designers and plastics application engineers who have had limited or no experience with plastics materials as well as a more experienced designer who is designing a part for a use, process or an application that they are not familiar with.

Knowledge of the properties of plastics is essential for designing products, specifying the material to be used, carrying out quality control on finished products, failure analysis and for understanding the structure and behaviour of new materials. Each class of materials has its own specific test procedures, which have developed as the material has evolved. This book concentrates on one area of testing - short-term mechanical tests. These are defined as tests of mechanical properties where the effects of long periods of time and cycling are ignored. This group of tests includes hardness, tensile, compression, shear, flexing, impact and tear and in this book it is also taken to include density and dimensional measurement together with test piece preparation and conditioning. This book will be useful to all those who are already involved in the testing of polymers and it is an ideal guide to those just starting out in the field, whether in academia or industry.

There are books aplenty on materials selection criteria for engineering design. Most cover the physical and mechanical properties of specific materials, but few offer much in the way of total product design criteria. This innovative new text/reference will give the “Big picture view of how materials should be selected—not only for a desired function but also for their ultimate performance, durability, maintenance, replacement costs, and so on. Even such factors as how a material behaves when packaged, shipped, and stored will be taken into consideration. For without that knowledge, a design engineer is often in the dark as to how a particular material used in particular product or process is going to behave over time, how costly it will be, and, ultimately, how successful it will be at doing what is supposed to do. This book delivers that knowledge. * Brief but comprehensive review of major materials functional groups (mechanical, electrical, thermal, chemical) by major material categories (metals, polymers, ceramics, composites) * Invaluable guidance on selection criteria at early design stage, including such factors as functionality, durability, and availability * Insight into lifecycle factors that affect choice of materials beyond simple performance specs, including manufacturability, machinability, shelf life, packaging, and even shipping characteristics * Unique help on writing materials selection specifications
