Abstract

Foam beads based on thermoplastic elastomers and having a coating comprising at least one electrically conductive substance, processes for producing same by coating the foam beads with an emulsion of a conductive substance in a plasticizer, and also processes for producing bead foams by joining the foam beads together thermally via high-frequency electromagnetic radiation.
