Sylomerpoly-urethane elastomers are special mate-rials designed to reduce vibration andstructure-borne noise.Depending on the requirements,these materials are available in a widerange of densities, thicknesses and dimensions. Their static load capacitylies between 0.005 N/mm2- 3.0 N/mm2(0.5 t/m2- 300 t/m2). Both the staticand dynamic characteristics of theseproducts are exactly defined, allowingthe effectiveness of the elastic suspen-sion to be calculated in advance.One typical application for Sylomeris as a direct bearing support for machinery(full-surface mount, strip bearings or discrete bearings).Weaving machine support leg: alayer of Sylomerunder the legs of theequipment reduce the transmission ofvibrations into the floor.Heat-power cogeneration: Sylomerstrip bearings under the equipmentframe lead to an excellent level of insulation for this heavy machinery. A customized elastic bearing is offeredfor each type of machine.Full-surface mount, strip bearings or discrete bearings.Maschinenprosp E.qxd15.04.2002 15:22 UhrSeite 5Adjustable machine stand: an elastic Sylomerdisk under the leg ofthe machine stand effectively insulatesagainst vibrations caused by motors,fans and pumps. The number of legson the stand can be varied dependingon the weight of the equipment. TheSylomerdisk is bonded to the floor-sideof the leg with a PUR coating, makingit easy to install.Machine stand with Sylomerelasticinsulated.Elastic insulation of HVAC equipment and other building equipment alsohinders the transmission of secondary airborne noise via ceilings and walls,leading to a significant reduction in noise in large-scale installations suchas schools, hospitals, hotels and production facilities.Maschinenprosp E.qxd15.04.2002 15:22 UhrSeite 6Elastically mounted floor slab:Example: Eco-culture industry cen-ter in FrankfurtA printers is situated in the ground floorof the building. The floor slab in thearea which house the material delivery,warehousing and cutting operations wasmounted on a full-surface L 25 Sylomerbearing, which means that the equip-ment can be moved around the areasubsequently without disturbance ofthe neighbourhood.Boilers:Mounting the boiler base ona full-surface Sylomerbearing can setthe tune of the foundation to a lowfrequency range.Example: Oasis casino and hotelin Jericho, the oldest city in theworldIn this building 32 machines of differenttypes (e.g. compressors, AC units,pumps, etc.) are housed on three floors. In order to minimize the level of vibra-tions caused by the equipment at thesource, a full-surface elastic Sylomerbearing was installed under the 25-cmbase foundation of the objects genera-ted the structure-borne noise.Large-scale foundation based onSylomer: Example: Volkswagen AGsCrash Test Facility in WolfsburgBy mounting the entire foundation on100 mm of Type M Sylomerit waspossible to tune the natural frequencyof the entire system to under 5 Hz,thereby protecting sensitive measure-ment and recording equipment (and itsoperating personnel) against vibrations.Machines whose mounting must be tuned to a lower frequency range or whichdevelop strong dynamic forces are usually mounted an additional base, suchas a machine mount or foundation. Sylomermaterials can be used in twoways in such applications: as active vibration insulation (to protect the sur-roundings) or as passive insulation (to protect the machine).Mounting on an additional baseFull-surface mount, strip bearings or discrete bearingson an additional base.Maschinenprosp E.qxd15.04.2002 15:23 UhrSeite 7Sylomermaterials are manufac-tured to meet the most stringentdemands. They must be suitable foruse in an enormously wide scope ofapplications, provide outstandinginsulation and withstand the extremeconditions of highly varied installa-tion sites.Getzner materials are tested both inter-nally by the quality control laboratoryand by internationally renowned institu-tions, in terms of their durability, qualityand effectiveness. Such tests have beenconducted by the following institutes: Federal Testing Centre Arsenal, Vienna, Austria Fraunhofer-Institute for Building Physics, Stuttgart, Germany Testing and Inspection Institute Vienna Municipal Works, Dept. 39, Austria Technical Inspection Association Rhineland, Institute for EnvironmentalProtection, Cologne, Germany Technical University of Munich, Chair and Institute for Road, Railway and Airfield Construction, Germany Mller-BBM GmbH, Planegg bei Munich, GermanySylomermaterials are resistant againstoils, greases, diluted acids and lyes andretain their elasticity even at very lowtemperatures.Sylomers unique cellular structure iscreated in a foaming process that doesnot use environmentally damaging foaming agents. The materials containno softeners. PUR materials can berecycled at Getzner.The physical and chemical properties ofGetzners products are documented inmaterial and products data sheets.
