This handbook is designed to support engineers in their efforts to develop practical solutions for industrial design and manufacturing challenges. It describes all classes of polymeric foams, including their chemistry, synthesis, commercial production methods, properties, and applications. Since the previous edition of this book, many of the industry’s most pressing problems―such as environmentally acceptable blowing agents, combustibility, and solid waste disposal―have been addressed and significant progress has been made. This edition reflects these developments as well as several new classes of foams brought to industrial application in recent years.
