Beschreibung
Zusammenfassung:	An extruded part comprising a substrate comprising at least one thermoplastic polymer, and a fire-retardant made of a fire-retardant material coating the substrate so that the external surface of the part exclusively consists of said fire-retardant material, wherein the fire-retardant layer adheres to the substrate, the fire-retardant material comprises a polyolefin and a non-halogenated fire-retardant compound, and the substrate comprises a mixture of a polyolefin and of at least one thermoplastic biopolymer and/or of at least one thermoplastic polymer, and an agent for compatibilization of the thermoplastic biopolymer and/or of the thermoplastic polymer with the polyolefin. A method for preparing said part by co-extrusion. Said part may notably be selected from among parts intended for handling and/or protecting cables and cable systems, such as trunkings and cable paths.
