Rubber compound for a vibration dampening device

摘要

The present invention provides a substantially gel-free compound comprising at least one elastomeric polymer comprising repeating units derived from at least one C4 to C7 isomonoolefin monomer, at least one C4 to C14 multiolefin monomer or beta -pinene, at least one multiolefin cross-linking agent and at least one chain transfer agent, at least one filler and a peroxide curing system. Another aspect of the invention is a vulcanized rubber part useful to dampen and/or isolate vibrations generated by mechanical devices comprising said substantially gel-free peroxide-curable compound. Yet another aspect of the invention is a mechanical device comprising a dynamic means which generates heat and/or vibrations and a static structure which supports said dynamic means and which is connected to said dynamic means and having a vulcanized rubber part comprising said substantially gel-free peroxide-curable compound interposed between said dynamic means and said static structure at said point of connection.
