OIL FIELD APPARATUS |
| 摘要 |
An oilfield apparatus includes a seal member. The seal member is formed of a rubber composition that includes a rubber, and at least either oxycellulose fibers or cellulose nanofibers that are dispersed in the rubber in an untangled state, and does not include an aggregate that includes at least either the oxycellulose fibers or the cellulose nanofibers and has a diameter of 0.1 mm or more. The rubber composition includes at least either the oxycellulose fibers or the cellulose nanofibers in a ratio of 1 to 60 parts by mass based on 100 parts by mass of the rubber. The oxycellulose fibers have an average fiber diameter of 10 to 30 micrometers. The cellulose nanofibers have an average fiber diameter of 1 to 200 nm. |
