Polymeric Foams Structure Property Performance

Polymeric Foams Structure–Property–Performance: A Design Guide is a response to the design challenges faced by engineers in a growing market with evolving standards, new regulations, and an ever-increasing variety of application types for polymeric foam. Bernard Obi, an author with wide experience in testing, characterizing, and applying polymer foams, approaches this emerging complexity with a practical design methodology that focuses on understanding the relationship between structure–properties of polymeric foams and their performance attributes. The book not only introduces the fundamentals of polymer and foam science and engineering, but also goes more in-depth, covering foam processing, properties, and uses for a variety of applications. By connecting the diverse technologies of polymer science to those from foam science, and by linking both micro- and macrostructure–property relationships to key performance attributes, the book gives engineers the information required to solve pressing design problems involving the use of polymeric foams and to optimize foam performance. With a focus on applications in the automotive and transportation industries, as well as uses of foams in structural composites for lightweight applications, the author provides numerous case studies and design examples of real-life industrial problems from various industries and their solutions.

Foaming of polymeric materials enables weight reduction, which is very important from the economic point of view, but most of all, it should be considered as an excellent means to provide new properties to various polymeric materials. Permanent developments in foaming technologies allow manufacturing of foams with micro- and even nano-sized pores, expanding the already very wide range of their applications. Except for the most conventional applications, which include damping materials, thermal and acoustic insulation, packaging materials or absorbents, applications in catalysis, fuel cells, tissue engineering, and electromagnetic shielding, often associated with nanocellular structures, have become more and more popular.Moreover, having in mind the ongoing trends and law regulations, it is important to remember the environmental impact of polymeric foams. Recent technological developments often involve biodegradability of foams, application of environmentally friendly raw materials, and innovative recycling methods.Because of the richness of potential innovations and future developments, the Editors are pleased to present the Structure, Properties and Applications of Polymeric Foams book, a collection of papers from Materials Special Issue dealing with the structure, performance, and applications of polymeric foams.

Polymers are among the major hallmarks of 20th-century science, and the explosive outgrowth and tremendous importance of polymeric foams is a testament to their amazing versatility and unique properties. With applications from automotive to acoustic and medical, polymeric foams pervade all areas of our lives. If this growth is to continue into the

Integral, or structural, foams are one of the most remarkable materials that have been developed over the last fifteen years. As with all rapidly growing fields, the terminology seems to have grown even faster. Thus there are two names for the material structure itself. In the United States and in Japan the term for these plastics is Structural Foams, whereas in Europe and the USSR the term used is usually Integral Foams. We have adhered to the European term in the text and hope our colleagues will bear with us. Integral foams have a specific structure: a cellular core that gradually turns into a solid skin. The skin gives the part its form and stiffness, while the cellular core contributes to the very high strength-to-weight values of the material. These are higher than those of some unfoamed plastics and metals. The sandwich-like structure with its unique mechanical properties was prompted by nature. Wood and bone are strong and light-weight natural materials having a cellular structure. Since the sandwich-like structure of the integral foams resembles that of natural wood, the foams are often referred to as artifical wood or plastic wood, thereby emphasizing not only the formal structural similarity of these materials, but also one of the main functional applications of integral foams - replacement of wooden articles in various fields of engineering and construction.

This Handbook reviews the chemistry, manufacturing methods, properties and applications of the synthetic polymer foams used in most applications. In addition, a chapter is included on the fundamental principles, which apply to all polymer foams. There is also a chapter on the blowing agents used to expand polymers and a chapter is on microcellular foams - a relatively new development where applications are still being explored.

Explores the Latest Developments in Polymeric Foams Since the 1960s polymeric foams have grown into a solid industry that affects almost every aspect of modern life. The industry has weathered the energy crisis in the 70s, ozone issues in the 80s, and recycle/reuse in the 90s. However, the pace of development and social climate is rapidly changing again, putting the spotlight even more firmly on performance, sustainable resources, and energy security. Coverage of New Products, Technologies, and Regulations Exploring new concepts, innovations, and developments in the field, Polymeric Foams: Technology and Development in Regulation, Process, and Products provides an international perspective on the direction of foam technologies and applications, focusing on the progress in blowing agent research and hydrofluorocarbons for the polyurethane foam industry. The text covers new foam products, including PP/PS interpolymer, nano-, and biodegradable foams. It also examines new technologies, such as injection foam molding and PVC foam; industry and environmental regulations; and research on foam performance, emission impact, and economic effects. Clearly Follows the Development Process As in most fields these days, efforts to be environmentally friendly and achieve enhanced performance for specialty applications drive research and development. Presenting a clear picture of the development process, this book covers not only new directions in the industry, but how they will impact current and future development.
