Vibration damping article

摘要

The present invention advances the art of vibration damping material constructions known to date. In one aspect of the present invention, a vibration damping article comprises at least one layer of polytetrafluoroethylene (PTFE). The vibration damping article of the present invention may also comprise at least one adhesive layer for mounting to an object of interest. The vibration damping article of the present invention may also comprise at least one constrained layer, such as a metal or polymer film layer, for example. The constrained layer may be adhered to the PTFE layer, with a layer of adhesive, or the constrained layer may be adhered with heat, pressure, ultrasonics or other laminating means, depending upon the constrained layer construction.
