摘要 |
The present invention provides a lubricant-feeding material which can be used at a temperature as high as from 100° C. to 120° 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.
