Selection Of Polymeric Materials

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.

The book is intended to reveal the correlation between the chemical structure and the physical characteristics of plastics necessary for appropriate material selection, design, and processing. The entire spectrum of plastics is addressed, including thermoplastics, thermosets, elastomers, and blends. One of the special features is the extensive discussion and explanation of the interdependence between polymer structure and properties and processing.

New edition brings classic text up to date with the latest science, techniques, and applications With its balanced presentation of polymer chemistry, physics, and engineering applications, the Third Edition of this classic text continues to instill readers with a solid understanding of the core concepts underlying polymeric materials. Both students and instructors have praised the text for its clear explanations and logical organization. It begins with molecular-level considerations and then progressively builds the reader's knowledge with discussions of bulk properties, mechanical behavior, and processing methods. Following a brief introduction, Fundamental Principles of Polymeric Materials is divided into four parts: Part 1: Polymer Fundamentals Part 2: Polymer Synthesis Part 3: Polymer Properties Part 4: Polymer Processing and Performance Thoroughly Updated and Revised Readers familiar with the previous edition of this text will find that the organization and style have been updated with new material to help them grasp key concepts and discover the latest science, techniques, and applications. For example, there are new introductory sections on organic functional groups focusing on the structures found in condensation polymerizations. The text also features new techniques for polymer analysis, processing, and microencapsulation as well as emerging techniques such as atom transfer radical polymerization. At the end of each chapter are problems—including many that are new to this edition—to test the reader's grasp of core concepts as they advance through the text. There are also references leading to the primary literature for further investigation of individual topics. A classic in its field, this text enables students in chemistry, chemical engineering, materials science, and mechanical engineering to fully grasp and apply the fundamentals of polymeric materials, preparing them for more advanced coursework.

Polymer Materials for Energy and Electronic Applications is among the first books to systematically describe the recent developments in polymer materials and their electronic applications. It covers the synthesis, structures, and properties of polymers, along with their composites. In addition, the book introduces, and describes, four main kinds of electronic devices based on polymers, including energy harvesting devices, energy storage devices, light-emitting devices, and electrically driving sensors. Stretchable and wearable electronics based on polymers are a particular focus and main achievement of the book that concludes with the future developments and challenges of electronic polymers and devices. Provides a basic understanding on the structure and morphology of polymers and their electronic properties and applications Highlights the current applications of conducting polymers on energy harvesting and storage Introduces the emerging flexible and stretchable electronic devices Adds a new family of fiber-shaped electronic devices

This book covers the theory of the strength of laminated and reinforced structures made of polymer materials with regard to the changeability of physico-chemical properties is examined. It presents an experimental-theoretical method on the definition of physico-mechanical properties of polymers composite materials and polymerized bundles made of fibers with emphasis on the changes of physico-chemical properties of the materials. With mathematical strictness, the experimental and theoretical studies presented here will aid in the development of reliable methods and new practices of analyzing structures with the influence of chemically aggressive liquids and gases and in the creation of specific production structures that will withstand corrosive environments.

This book collects the articles published in the Special Issue “Polymeric Materials: Surfaces, Interfaces and Bioapplications”. It shows the advances in polymeric materials, which have tremendous applications in agricultural films, food packaging, dental restoration, antimicrobial systems, and tissue engineering. These polymeric materials are presented as films, coatings, particles, fibers, hydrogels, or networks. The potential to modify and modulate their surfaces or their content by different techniques, such as click chemistry, ozonation, breath figures, wrinkle formation, or electrospray, are also explained, taking into account the relationship between the structure and properties in the final application. Moreover, new trends in the development of such materials are presented, using more environmental friendly and safe methods, which, at the same time, have a high impact on our society.
