This unique introduction covers both low- and high-density thermoplastic foams in an easy-to-follow style that avoids excursions into the theoretical aspects of foam processing.
As researchers seek replacements for banned, ozone-depleting foaming agents, the authors of Thermoplastic Foam Processing: Principles and Development strive to develop a better understanding of foaming processes and find solutions for day-to-day practice. This book presents the latest research in foam extrusion and physical foaming agents with a strong focus on the interaction of material components in the foaming process. As part of the Polymeric Foams series and a companion to the volume, Foam Extrusion: Principles and Practice (2000), the book includes new topics such as polymer blends and mechanical properties, and further develops several vital topics appearing in Foam Extrusion, such as extensional rheology and solubility/diffusivity. The text also addresses factors that affect the critical interaction between polymer and gas in the foaming process, such as polymer plasticization, gas dissolution, phase separation, foaming, and stabilization. Written by experts, the book provides clear information on the mechanisms and the practical conditions experienced during nucleation and cell growth. In the midst of new research for alternative, environmentally friendly foaming agents, Thermoplastic Foam Processing: Principles and Development gives the reader a clear understanding of the current trends in R & D and an up-to-date review of the state of the art in thermoplastic foam processing. This book provides useful tools for the development and validation of innovative physical foaming agent and polymer combinations for current and future research.
Combining the science of foam with the engineering of extrusion processes, Foam Extrusion: Principles and Practice delivers a detailed discussion of the theory, design, processing, and application of degradable foam extraction. In one comprehensive volume, the editors present the collective expertise of leading academic, research, and industry spec
The purpose of this book is to help you concentrate on recent developments in polymerization. The chapters collected in the book are contributions by invited researchers with a long-standing experience in different research areas. I hope that the material presented here is understandable to a broad audience, not only chemists but also scientists from various disciplines. The book contains nine chapters in three sections: (1) "General Information about Polymerization," (2) "Biomaterial Content Polymer Composites," and (3) "Mechanical Properties of Polymerization." The book provides detailed and current reviews in these different areas written by experts in their respective fields. This book is expected to be useful for polymer workers and other scientists alike and contribute to the training of current and future researchers, academics, PhD degree students, as well as other scientists.
Polymeric foams are sturdy yet lightweight materials with applications across a variety of industries, from packaging to aerospace. As demand for these materials increase, so does innovation in the development of new processes and products. This book captures the most dynamic advances in processes, technologies, and products related to the polymeric foam market. It describes the latest business trends including new microcellular commercialization, sustainable foam products, and nanofoams. It also discusses novel processes, new and environmentally friendly blowing agents, and the development and usage of various types of foams, including bead and polycarbonate, polypropylene, polyetherimide microcellular, and nanocellular. The book also covers flame-retardant foams, rigid foam composites, and foam sandwich composites and details applications in structural engineering, electronics, and insulation. Authored by leading experts in the field, this book minimizes the gap between research and application in this important and growing area.
This book is the inaugural volume a series entitled Polymeric Foams: Technology and Applications. Generally, thermoplastic and thermoset foams have been treated as two separate practices in industry. Polymeric Foams: Mechanisms and Materials presents the basics of foaming in general build a strong foundation to those working in both thermoplastic a
Practical and affordable, thermoplastics account for more than 90 percent of all plastic materials manufactured. That so many varieties are now available, speaks to the idea that while there is no one perfect material, it is possible to find a material that fits for every application. However, selecting that right material is no small challenge. Answering the needs of manufacturers and product developers, Thermoplastic Materials: Properties, Manufacturing Methods, and Applications provides all the information required to confidently select the right thermoplastic for any application. Based on a course taught to engineering students, the book starts with an overview of the plastics industry, looking at the major companies involved and how their products influence society. It then discusses various topics essential to the understanding and manufacturing of thermoplastics before getting to the core of the book, more than 400 pages of consistently formatted entries, organized according to 19 thermoplastics families and groupings. Each chapter covers raw materials, manufacturing methods, properties, costs, and applications. Among many topics related to thermoplastic resins, this seminal work: Provides micro and quasi-macro perspectives on their behavior Evaluates major manufacturing methods Discusses crystallinity and permeability Elaborates on the properties that make them useful barrier and packaging materials Written by Christopher Ibeh, professor of plastics engineering technology and director of the Center for Nanocomposites and Multifunctional Materials at Pittsburg State University, this book goes beyond current practices to look at emerging materials, including nanocomposites, and discusses sustainability as it relates to plastics. It also includes a chapter on functionalized thermoplastics, written by Andrey Beyle.
Special Injection Molding Techniques covers several techniques used to create multicomponent products, hollow areas, and hard-soft combinations that cannot be produced with standard injection molding processes. It also includes information on the processing techniques of special materials, including foaming agents, bio-based materials, and thermosets. The book describes the most industrially relevant special injection molding techniques, with a detailed focus on understanding the basics of each technique and its main mechanisms, i.e., temperature, mold filling, bonding, residual stresses, and material behavior, also providing an explanation of process routes and their variants, and discussions of the most influencing process parameters. As special molding technologies have the potential to transform plastics processing to a highly-efficient, integrated type of manufacturing, this book provides a timely survey of these technologies, putting them into context, accentuating new opportunities, and giving relevant information on processing.
