Abstract

Die Erfindung betrifft ein mehrschichtiges Rohrformteil, insbesondere mehrschichtiges Rohr 1 mit einer Wandung 1.1, die eine erste Schicht 1.1.1 aufweist, die ein Polymermaterial enthält oder aus einem Polymermaterial besteht, wobei das Polymermaterial ausgewählt ist aus einem Thermoplasten, und einer mit dieser verbundenen zweiten Schicht 1.1.2, die ein Polymermaterial enthält oder aus elnem Polymermaterial besteht, wobei das Polymermaterial ausgewählt ist aus einem Thermoplasten, das sich dadurch auszeichnet, dass das Polymermaterial der zweiten Schicht 1.1.2 geschlossenzellige Hohlräume aufweist und eine Dichte besitzt, die um 5 bis 15 % gegenüber der Dichte des Polymermaterials, das keine Hohlräume aufweist, reduziert ist und dass die Dicke der zweiten Schicht 1.1.2 5 bis 25 % der Dicke der ersten Schicht 1.1.1 beträgt.The invention relates to a multilayer pipe molding, in particular a multilayer pipe 1 having a wall 1.1, which comprises a first layer 1.1.1 containing a polymer material or consists of a polymer material, wherein the polymer material is selected from a thermoplastic, and a second associated with this Layer 1.1.2, which contains a polymer material or consists of a polymer material, wherein the polymer material is selected from a thermoplastic, which is characterized in that the polymer material of the second layer 1.1.2 has closed-cell cavities and has a density of 5 to Is 15% less than the density of the polymer material having no voids, and that the thickness of the second layer 1.1.2 is 5 to 25% of the thickness of the first layer 1.1.1.
