To provide a molded body that has sufficient flexibility and can suitably be used as a blade rubber in which the influence from bleeding liquid on wiping-surface is suppressed.SOLUTION: Provided is a silicone rubber molded body 1, made of a silicone rubber containing a platinum-based catalyst and having a crosslink structure and in which the crosslink structure is composed of a first crosslink structure derived from polyorganohydrogensiloxane and a second crosslink structure derived from a compound having 2 or more ethylenically unsaturated bonds in the molecule, and having a region with hardness distribution in which hardness gradually decreases from the surface toward the depth direction.SELECTED DRAWING: Figure 1
【課題】十分な柔軟性を有し、かつ、ブリード液による払拭面への影響が抑制されたブレードラバーとして好適に用いることができる成形体を提供する。【解決手段】白金系触媒を含み、架橋構造を有するシリコーンゴムからなり、架橋構造が、ポリオルガノハイドロジェンシロキサンに由来する第1架橋構造と、分子内に2以上のエチレン性不飽和結合を有する化合物に由来する第2架橋構造からなり、表面から深さ方向に向かって徐々に硬度が低くなる硬度分布を有する領域を備えるシリコーンゴム成形体1とする。【選択図】図1
