Beschreibung
Zusammenfassung:	An injection moulded or extruded pipe part of thermoplastic material with sound-proofing properties having a weight per unit area of at least 8 kg/m . The weight per unit area is adjusted by incorporating a filler in the plastic, preferably barium sulphate is used as such a filler. The density of the plastic pipe part is comprised between 1.4 and 2.7, preferably between 1.8 and 2.0 g/cm . Suitable thermoplastic materials are PVC, polyolefins and ABS (acrylonitrile-butadiene-styrene) copolymer, particularly PVC or polypropylene. The plastic pipe part may also be a socket or a double sided socket. The pipe parts are particularly suitable for forming a waste pipe system.
