  • Rubber compound for a vibration dampening device
    Publication number: 20040014904
    Abstract: The present invention provides a substantially gel-free compound containing at least one elastomeric polymer having repeating units derived from at least one C4 to C7 isomonoolefin monomer, at least one C4 to C14 multiolefin monomer or &bgr;-pinene, at least one multiolefin cross-linking agent and at least one chain transfer agent, at least one filler and a peroxide curing system. The present invention also provides vulcanized rubber part useful to dampen and/or isolate vibrations generated by mechanical devices containing the substantially gel-free peroxide-curable compound. The present invention further provides a mechanical device containing a dynamic means which generates heat and/or vibrations and a static structure which supports the dynamic means and which is connected to the dynamic means and having a vulcanized rubber part containing the substantially gel-free peroxide-curable compound interposed between the dynamic means and the static structure at a point of connection.
