Title:
FLUORORUBBER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/009641
Kind Code:
A1
Abstract:
A fluororubber composition which comprises 100 parts by weight of a fluororubber, 5-30 parts by weight of a carbon black having an iodine adsorption of 70 mg/g or greater, 5-20 parts by weight of carbon fibers having an average fiber diameter of 5-20 μm and an aspect ratio of 2-10, and 3-20 parts by weight of PTFE. This fluororubber composition exhibits excellent effects wherein a crosslinked molded object obtained therefrom has oil-film retentivity imparted by the use of the carbon fibers, which have the specific properties, and has improved wear resistance in a non-lubricated situation due to the use of a combination of the carbon fibers and the PTFE as a solid lubricating agent.
