The present invention relates to a particulate, expandable polymer, for example polystyrene (EPS) or polylactic acid (PLA) or a combination thereof, which can be processed to form a foam having a fine cell structure and a low density, and which contains a thermal insulation value-increasing material so as to increase the thermal insulation value thereof The present invention further relates to a method for producing such particulate, expandable polymer, as well as to a foam material based on such a polymer. |
