A fluororubber composition comprising 10 to 50 parts by weight of wollastonite and 0.5 to 10 parts by weight of organic peroxide based on 100 parts by weight of peroxide-crosslinkable fluororubber,n the wollastonite being needle-like or fibrous wollastonite having an average fiber diameter of 5 μm or less and an average fiber length of 40 to 80 μm, and the wollastonite being surface-treated with an amino silane coupling agent or an epoxy silane coupling agent. The fluororubber composition that can be suitably used as, for example, a molding material for normal/reverse rotation oil seals that allow continuous excellent sealing of fluid in the operation of normal and reverse rotation. |
