Abstract: A production process can produce foam materials from a polymer composition. This production process may involve preheating a polymer composition to be foamed. The preheated composition may then be foamed by a thermal process assisted by microwaves. The foaming may occur in an apparatus that has a heating device. The polymer composition may contain a blowing agent.
