SCHWINGUNGSDAEMPFENDES MATERIAL.

摘要

A vibration-damping material consisting of two metal plates and a vibration-damping layer of thermoplastic resin interposed between the two metal plates, in which said thermoplastic resin has a percentage of wlongation at 20 DEG C. of 30% or more, preferably 50% or more, a peak temperature of dissipation factor (tan delta ) in the range of -50 DEG C. to 130 DEG C., and a bonding strength toward the metal plates of 3 kg/cm or more as determined by 180 DEG -peeling test at 20 DEG C.
