摘要: Multi-layer composites, particularly thermoplastic composites, in form of an extruded hollow section, e.g. tubes or hoses for liquid fuel lines, include a thermoplastic outer layer and at least one further layer, whereinthe outer layer is formed by a mixture based on (A) 80 to 20 parts by weight of at least one polyamide (PA) and (B) 20 to 80 parts by weight of at least one polyamide elastomer (TPE-A), of polyether amides, polyester amides, polyether ester amides, polyether ester ether amides or mixtures thereof, wherein the sum of (A) and (B) is 100 parts by weight, the hollow section being produced at extrusion speeds, of over 20 m/min, so that the produced hollow section has an elongation at break, of over 200%, wherein the elongation at break has been measured at the finished hollow section according to DIN EN ISO 527-2.
