Abstract
A vibration damper material 1 composed of a laminated sheet having a base stock layer 3, a resilient layer 4, an primer layer 5, an organic component barrier layer 6 and an adhesive layer 7 successively laminated in that order from one to the other side thereof, and a release liner 8 stuck on the adhesive layer 7. The resilient layer 4 is constituted by a resilient material containing a vehicle consisting of a member or a mixture of two or more members selected from the group of asphalt, rubber, synthetic resins and cellulose derivatives, synthetic resin powder, and an elastic material having an elongation rate of 500% or higher. The organic component barrier layer functions to block permeation therethrough of organic components such as tar and oil components which would otherwise tend to migrate into the adhesive layer from the resilient layer. Despite a substantial reduction in thickness, the vibration damper sheet possesses satisfactory vibration damping properties, along with excellent adhesion to curved surfaces and punching machinability and sticking machinability.
