This volume investigates the use of polymer blends in foam processing, mechanical properties and morphology of thermoplastic foams, extensional rheology, and solubility/diffusivity. It also addresses the factors that affect the critical interaction between polymer and gas in the foaming process, including polymer plasticization, gas dissolution, phase separation, foaming, and stabilization. The book provides clear information on the mechanisms and the practical conditions experienced during nucleation and cell growth, as well as useful tools for the development and validation of innovative physical foaming agent/polymer combinations for current and future research.

From the Preface: “...[E]xperimentations were addressed with practical concerns in mind, as...researchers interacted closely with the field practitioners. Nevertheless, part of their preoccupation in writing the manuscript was to provide the reader with useful tools that could be relevant for foam development and, moreover, to suggest fresh and innovative ideas that would still need dedicated efforts to be explored. These ideas should provide potential work for the next 10 years.”

Target Audience: Materials scientists and engineers; polymer technologists; designers in the packaging and automotive industries; and other professionals involved in the development, manufacture, or end use of thermoplastic foams.
