Abstract
Polymeric foams have become an intrinsic component in domestic and industrial applications worldwide. Because of that, understanding their properties, how they are processed, and the predominant materials involved in their manufacturing are important to guide young scientists to comprehend the main concepts and aspects of polymeric foams. This introductory chapter starts with a discussion regarding the importance of the dominant polymeric foams and their influence in the global market. The main concepts regarding foaming processes and formulations to tailor their properties are also covered. The second section covers the main types of polymeric foams along with some of the chemistry involved in their manufacturing and their general properties. The third section is focused on the fabrication methods of polymeric foams along with the main materials employed for each method and their respective advantages and disadvantages. The fourth section covers the main applications of polymeric foams. It provides examples from literature to describe how scientists have been further improving the properties of foams and expanding their ranges of applications. Based on the covered topics, this chapter is focused on providing the core information required for any scientists in polymeric foams to properly understand and develop products that can potentially be used in the industry.
