COMPOSITE ELASTIC MATERIAL AND ELASTIC COMPOSITION
To provide a composite elastic material excellent in workability, and excellent in characteristics (Impact absorption and vertical displacement resistance), and to provide an elastic composition for obtaining the composite elastic material.SOLUTION: In a composite elastic material 1 including an elastic layer 2 containing an elastic resin 5 and a foaming tip 6, and a durability layer 3 arranged on the elastic layer 2 and having higher hardness than the elastic layer 2, the elastic resin 5 is a hardened product of an elastic composition in which Ti value is 1.4 or more and 2.4 or less. T1 value=viscosity η1 measured in condition 1/viscosity η2 measured in condition 2. Condition 1: temperature 25°C and shear velocity 6 rpm. Condition 2: temperature 25°C and shear velocity 60 rpm.SELECTED DRAWING: Figure 1
【課題】作業性に優れ、優れた物性（衝撃吸収性および垂直変位量耐性）を有する複合弾性材、および、複合弾性材を得るための弾性組成物を提供する。【解決手段】弾性樹脂５および発泡体チップ６を含む弾性層２と、弾性層２の上に配置される、弾性層２よりも高硬度の耐久層３とを備える複合弾性材１において、弾性樹脂５が、ＴＩ値１．４以上２．４以下の弾性組成物の硬化物である。ＴＩ値＝条件１で測定される粘度η１／条件２で測定される粘度η２条件１：温度２５℃、せん断速度６ｒｐｍ条件２：温度２５℃、せん断速度６０ｒｐｍ【選択図】図１
