Abstract
A fluororubber composition comprising 3 to 20 parts by weight of carbon fibers and 1 to 8 parts by weight of carbon nanotubes based on 100 parts by weight of fluororubber. The crosslinked molded article obtained from the fluororubber composition has excellent effects of not only imparting oil film retention, but also improving the material strength of fluororubber due to the combined use of carbon nanotubes, which have high reinforcing properties. Further, the fluororubber composition can give a fluororubber crosslinked product excellent in abrasion resistance and pressure resistance.
