Polypropylene Foams: Production, Structure and Properties (original) (raw)

Abstract

It is well known the relevance given to the study of heat transfer in polymer foams, as one of the main applications is as lightweight thermal insulating elements. Alongside some of the possible strategies for improving the thermal insulating characteristics of polymer foams, there is also a tremendous interest in further extending the applications of these materials, mainly focusing on improving their poor mechanical properties. Although there is a great deal of interest in preparing and studying polypropylene foams, largely due to their good balance of properties and reduced cost, there is still lack of information regarding their mechanical and thermal conduction characterizations. With that in mind, this chapter considers the preparation, structure and properties of different polypropylene and polypropylene-based nanocomposite foams, focusing on the importance of the foam’s cellular structure and microstructure characteristics and/or filler’s orientation and dispersion in the me...
