    • The present invention provides a lubricant-feeding material which can be used at a temperature as high as from 100null C. to 120null C., exhibits an excellent mechanical strength and stably maintains a lubricating oil having a high polarity such as ester oil and polyphenylether oil, which have excellent lubricating properties or heat resistance, or a grease comprising such a lubricating oil as a base oil in a large amount. The lubricant-feeding material comprises a polyester elastomer comprising a hard component made of a first polyester and a soft component made of a second polyester or polyether solidified containing a lubricating oil compatible with the polyester elastomer or a grease comprising the lubricating oil as a base oil, the lubricating oil oozing from the surface of the polyester elastomer.
    • 本发明提供一种润滑剂供给材料,其可以在100℃至120℃的高温下使用,显示出优异的机械强度并稳定地保持高极性的润滑油,例如酯油和 具有优异的润滑性或耐热性的聚苯醚油,或者含有大量基础油等润滑油的润滑脂。 润滑剂供给材料包括聚酯弹性体,其包含由第一聚酯制成的硬质组分和由固化的第二聚酯或聚醚固化的软组分,所述第二聚酯或聚醚固化含有与聚酯弹性体相容的润滑油或包含润滑油作为基础油的润滑脂 ,润滑油从聚酯弹性体的表面渗出。
