Title: SEALING MEMBER
Abstract:
[Problem] To provide a ring-shaped sealing member having both sealability and slidability. [Solution] The present invention provides a ring-shaped sealing member having a sliding surface. The sealing member contains 100 parts by weight of a fluorine-based rubber and 0.5-50 parts by weight of a particulate resin. The particulate resin includes a compatible portion having compatibility with respect to the fluorine-based rubber and a lubricant portion having lubricity with respect to the fluorine-based rubber. The Shore A hardness measured with the sliding surface serving as a pressing surface is at least 80. Since rubber elasticity is obtained by the fluorine-based rubber, this sealing member can exhibit good sealability. In addition, it is possible to impart high slidability to the sealing member through the action of the lubricant portion of the particulate resin. Therefore, this sealing member has both sealability and slidability.
