Abstract

An extruded or injected plastic tube, containing fillers to improve acoustic insulation properties has ≥ 2 adjoining coaxial layers (1,2) showing a common surface. They are an outer layer (1) of conventional plastic and an inner layer (2) containing a filler to at least improve acoustic insulation properties.
