The conference was dedicated to the critical role of blowing agents in foamed plastics and rubber. Foamed materials are being enhanced to replace dense solid polymers, reducing weight and costs. Chemical and environmental legislation is constantly changing and the foam industry is adapting to meet demands. The proceedings include papers from industry leaders such as BASF AG, Solvay, 3M Europe, Zotefoams plc and Trexel GmbH and will appeal to those involved in the formulation and application of blowing agents and techniques to produce expanded or foamed polymer substrates.
