Beschreibung
Zusammenfassung:	A composition for the production of a sealing element which may be softened or melted by inductive and/or capacitative heating comprises one or more thermoplastic polyolefin polymers, one or more thermoplastic olefin-vinylester copolymers and particles of one or more inductive and/or capacitative materials. For preference, the polyolefin is polyethylene, polypropylene, polyethylene-copropylene, polybutylene, polyhexylene or polyoctylene; the olefin-vinylester is preferably ethylene-vinyl acetate (EVA) whilst the inductive/capacitative material is aluminium, copper or alloys of either, magnetic oxides of iron or chromium.
