PROBLEM TO BE SOLVED: To provide a multilayer structure elastomer molded article or a weather strip in which bleeding is suppressed in a coating body formed on a surface of a substrate and desired sliding property and wear resistance are achieved.SOLUTION: A first thermoplastic elastomer material prepared by compounding, kneading and crosslinking at least a rubber component, an olefin resin material, and a crosslinking agent, and a second thermoplastic elastomer material prepared by compounding, kneading and crosslinking at least a rubber component, an olefin resin material, a crosslinking agent, and a lubricant, are molded by extrusion to form a substrate 10 made of the first thermoplastic elastomer material and a coating body 6 made of the second thermoplastic elastomer material is formed on a surface of the substrate 10. Weight percentages A, B of a softening agent included in the first and second thermoplastic elastomer materials, respectively, are controlled to satisfy a ratio B/A of B to A ranging from 0.00 to 0.30; and a crosslinking degree of the coating body is controlled to 90% or more.

    【課題】基体の表面に形成される被覆体においてブリードが抑制され所望の摺動性,耐磨耗性を有した多層構造エラストマー成形体又はウェザーストリップの提供。【解決手段】少なくともゴム成分,オレフィン系樹脂材料,架橋剤を配合して混練し架橋された第1の熱可塑性エラストマー材料と、少なくともゴム成分,オレフィン系樹脂材料,架橋剤,滑剤を配合して混練し架橋された第2の熱可塑性エラストマー材料と、を押出し成形して、第1の熱可塑性エラストマー材料から成る基体10の表面に第2のエラストマー材料から成る被覆体6を形成する。第1,第2の熱可塑性エラストマー材料それぞれに含まれる各軟化剤の重量百分率をそれぞれA,Bとした場合にAに対するBの比B/Aを0.00〜0.30とし、被覆体の架橋度を90%以上にする。【選択図】図1
