DAMPING MATERIAL

摘要

A damping material having excellent damping and lightweight characteristics, especially a damping material that can find suitable application in automobile uses wherein light weight is demanded. There is provided a damping material characterized in that a foam adhesive layer is superimposed on one major surface of a thermoplastic resin foam sheet and unified. Thus, the damping material exerts excellent damping property such that any vibrational energy conveyed to the damping material is smoothly absorbed by a synergistic effect of rigidity of the thermoplastic resin foam sheet with viscoelasticity of the foam adhesive layer. Moreover, this damping material excels in weight saving, so that it can find suitable application in uses wherein light weight is demanded, for example, uses for vehicles such as automobiles and railways and due to light weight, excels in workability.
