DAMPING MATERIAL
To provide a damping material that has excellent damping properties and has excellent followability to an irregular or curved surface.SOLUTION: A damping material has a resin layer (1), and a constraint layer (2) laminated on the resin layer (1). The resin layer (1) is composed of foam of an olefin polymer (A). The foam has at least one peak of loss tangent tanδ by dynamic viscoelasticity measurement in a temperature range of 0°C or higher and 40°C or lower.SELECTED DRAWING: None
【課題】制振性に優れ、かつ凹凸を有するかまたは曲面である表面への追従性に優れた制振材を提供すること。【解決手段】樹脂層（１）と、前記樹脂層（１）に積層された拘束層（２）とを備え、前記樹脂層（１）が、オレフィン系重合体（Ａ）の発泡体からなり、前記発泡体が、動的粘弾性測定により求められる損失正接ｔａｎδのピークを０℃以上４０℃以下の温度範囲に１つ以上有する、制振材。【選択図】なし
