RESIN COMPOSITION FOR SLIDING MEMBER, EXTRUSION MOLDING, COMPONENT FOR AUTOMOBILE, AND WEATHER STRIP

To provide a resin composition for a sliding member which is excellent in followability and slidability under a high load, and is also excellent in moldability and workability, and an extrusion molding, a component for an automobile and a weather strip which are made of the resin composition for the sliding member.SOLUTION: A resin composition for a sliding member contains a non-crosslinked olefinic resin component including a propylene unit and an ethylene unit, and polyorganosiloxane, wherein the polyorganosiloxane is composed of polyorganosiloxane (P1) having dynamic viscosity (25°C) of 100,000 mm2/s or more and polyorganosiloxane (P2) having dynamic viscosity (25°C) of 50,000 mm2/s or less. There is also provided an extrusion molding of the resin composition for the sliding member. A component for an automobile has the resin composition for the sliding member. A weather strip has a base material, and a sliding member made of the resin composition for the sliding member.SELECTED DRAWING: Figure 1 【課題】追従性と高荷重下での摺動性に優れ、かつ成形性と加工性にも優れる摺動部材用樹脂組成物と、この摺動部材用樹脂組成物よりなる押出成形体、自動車用部品、及びウェザーストリップを提供する。【解決手段】プロピレン単位とエチレン単位を含む非架橋のオレフィン系樹脂成分と、ポリオルガノシロキサンとを含有する摺動部材用樹脂組成物であって、前記ポリオルガノシロキサンが、動粘度（２５℃）１００，０００ｍｍ２／ｓ以上のポリオルガノシロキサン（Ｐ１）と、動粘度（２５℃）５０，０００ｍｍ２／ｓ以下のポリオルガノシロキサン（Ｐ２）より成る摺動部材用樹脂組成物。この摺動部材用樹脂組成物の押出成形体。この摺動部材用樹脂組成物を備えた自動車部品。基材とこの摺動部材用樹脂組成物よりなる摺動部材とを具備するウェザーストリップ。【選択図】図１
