A process and apparatus are described for extruding a soft, low density elastomeric thermoplastic foam. A single screw extruder having a very large screw length to diameter ratio is provided to thoroughly mix the thermoplastic elastomer with a blowing agent. A thin, substantially taperless die is also provided to form extruded profiles. By using such a process and apparatus, a variety of complex-shaped extruded profiles may be easily produced.
