  • Publication number: 20130320604
    Abstract: Provided is a viscous-fluid-enclosing damper which attenuates, by using viscous resistance of a vibration-damping composition, vibrations transmitted between a support and an object to be supported, the support and object being attached to a closed container enclosing the vibration-damping composition of a viscous fluid. The viscous-fluid-enclosing damper alters few vibration-damping properties even when used under high temperatures and/or conditions where the vibrations are repeatedly generated for a prolonged period. Also provided is the vibration-damping composition which is used for the viscous-fluid-enclosing damper. The viscous fluid contains a viscous liquid having dispersed therein at least one type of heat-resistant resin particles and a dripping inhibitor, the particles being selected from polyethylene and nylon having an average molecular weight of from 50×104 to 600×104 and an average particle size of from 10 ?m to 200 ?m and preferably from 10 ?m to 160 ?m.
