| description | To provide a polyurethane foam exhibiting a moderately low hardness while maintaining excellent rebound resilience, and excellent in mechanical strength, to provide a shoe sole member obtained by using the polyurethane foam, and to provide a shoe sole in which an arbitrary part or the whole is constituted by using the polyurethane foam as the shoe sole member.SOLUTION: A polyurethane foam comprises a polyol component, a polyisocyanate component, a foaming agent, a catalyst, and a foam stabilizer, and the polyol component contains a polytetramethylene ether glycol having a number average molecular weight of 600 or more and 3,000 or less, and a polypropylene glycol. The polyurethane foam is formed so that a ratio of the polytetramethylene ether glycol to the polypropylene glycol in the polyol component is polytetramethylene ether glycol:polypropylene glycol=95:5-55:45. A shoe sole is constituted by using the polyurethane foam as a shoe sole member.SELECTED DRAWING: None
【課題】良好な反発弾性を維持しつつ、適度に低い硬度を示し、かつ機械的強度にも優れるポリウレタンフォーム、および当該ポリウレタンフォームを用いてなる靴底部材および任意の部分または全体が、本発明のポリウレタンフォームを靴底部材として用いて構成された靴底を提供する。【解決手段】ポリオール成分、ポリイソシアネート成分、発泡剤、触媒、整泡剤を含み、ポリオール成分は、数平均分子量が６００以上３０００以下であるポリテトラメチレンエーテルグリコール、およびポリプロピレングリコールを含み、ポリオール成分中のポリテトラメチレンエーテルグリコールとポリプロピレングリコールの比率が、ポリテトラメチレンエーテルグリコール：ポリプロピレングリコール＝９５：５〜５５：４５となるようポリウレタンフォームを構成し、また当該ポリウレタンフォームを靴底部材として用いて靴底を構成する。【選択図】なし |
