Abstract

A process for expanding a thermoplastic polymer, comprising heating a composition comprising a thermoplastic polymer, preferably one with a treatment temperature greater than 200ºC, and a blowing agent to cause thermal decomposition of the blowing agent, and wherein As the primary blowing agent, zinc carbonate and/or cadmium carbonate are used, and preferably a nucleating agent is also present, particularly a particular solid with an average particle size of less than 100 microns.
