Sound-absorbing extruded or sprayed or blow-molded compact, multilayer domestic installation pipe or domestic installation shaped part
By Heinrich, Gerhard
From Ger. Offen. (2006), DE 102005021933 A1 20061221.  |  Language: German, Database: CAPLUS
Multilayeredsound-absorbing pipes and shaped parts for domestic installation comprising a core, compact thermoplastic layer with diam. 1 - 3 mm having ≤67 wt.% BaSO4 as a filler coated with a thermoplastic foamed layer having thickness 1.5 - 3 mm and pore diam. 50 - 100 μm are manuf. by coextruding, spraying or blow molding.

2. Refractory multilayer pipes with good sound insulationFull Text
By Okada, Kazuhiro; Tono, Masaki
From Jpn. Kokai Tokkyo Koho (2006), JP 2006161982 A 20060622.  |  Language: Japanese, Database: CAPLUS
Title pipes comprise a synthetic resin pipe and a thermal expandable refractory layer having sound insulation property formed on the circumferences of the pipe.  Thus, a sound insulation material comprising Vistanex MML 80 70, Polybutene HV 100 20, I-Marv P 125 10, and titanium oxide 200 parts was extruded and wraped on the circumference of the polyvinyl chloride pipe, a thermal expandable material comprising Bu 065 (butyl rubber) 42, Polybutene HV 100 50, I-Marv P 125 8, Exolit AP 422 100, Flame Cut GREP-EG 30, B 325 (aluminum hydroxide) 50, and BF 300 (calcium carbonate) 100 parts was extruded and wraped thereon to give a test piece, showing good flame resistance and sound insulation.

3. Non-combustible multilayer material for transportable buildingsFull Text
No Inventor data available
From Ger. Gebrauchsmusterschrift (2005), DE 202005010794 U1 20051103.  |  Language: German, Database: CAPLUS
A flame retarding, thermally and sound insulating, multilayer composite material, suitable as construction parts (frames, e.g.) of tents or fair buildings, is preferably made of two structured surface layers of PVC, sepd. by a non-combustible interlayer of mineral wool or perlite, which, optionally, embeds a core layer of expanded or extruded polystyrene or polyurethane, wherein the single plies are at least partially adhered to each other.

4. Extruded multilayer pipes with suppressed vibration caused by flowing liquidFull Text
By Amanomiya, Kazuhiro
From Jpn. Kokai Tokkyo Koho (2003), JP 2003053815 A 20030226.  |  Language: Japanese, Database: CAPLUS
The pipe, useful for plumbing, comprises (A) a core pipe part, (B) a vibration-damping sound-insulator layer of flexible resins extruded around the core, and (C) an outer layer of hard resins extruded around the insulator layer.  The sound insulator layer may have a honeycomb-like cross section or a cross section comprising circle holes or rectangular holes.
