Abstract:
Laser-markable foamed pellets contain a composition (MI), containing a thermoplastic elastomer (TPE-1) and a color component as component (c1) selected from laser marking additives. A process can be used for producing said laser-markable foamed pellets. The laser-markable foamed pellets according to the present invention can be used for preparing a laser-markable molded body. A process for preparing a laser-markable molded body involves providing and fusing the laser-markable foal led pellets.
