摘要： Object: To provide fluororubber compositions and crosslinked fluororubber products that are suitable for use as rotary shaft seals, in which each of the initial characteristics, i.e., torque reduction (reduced friction) and sealing properties attributed to reduced oil leakage (oil pump rate when the seal member slides), can be improved, and degradation of these characteristics can be inhibited even after frictional abrasion.Solution Means: A fluororubber composition obtained by blending a polyol crosslinking agent into a fluororubber polymer including 70 to 90 wt % of a polyol-crosslinkable fluororubber polymer (A) and 30 to 10 wt % of a peroxide-crosslinkable fluororubber polymer (B); and a fluororubber composition obtained by blending a polyol crosslinking agent and a peroxide crosslinking agent into a fluororubber polymer including 40 to 90 wt % of a polyol-crosslinkable fluororubber polymer (A) and 60 to 10 wt % of a peroxide-crosslinkable fluororubber polymer (B).

The oil seal comprises a seal lip (4) formed of a rubber-like elastic material comprising a lip edge part (9) and an air-side slope (8) and a sealing fluid-side slope (10) provided on both sides of the lip edge part (9). The air-side slope (8) has a coating film (14) on its surface. In the lip edge part (9) in its portion in contact with a shaft (13), a sealing fluid-side rubber part (2′) and an air-side coating film (14) are simultaneously brought into contact with the shaft (13). The coating film (14) is preferably formed of a coating agent comprising a fluororesin, a polyethylene resin, an isocyanate-modified polybutadiene resin, and a solvent.
