Publication number: 20200056029Abstract: [Object] To provide a technology for imparting favorable slidability to fluorine rubber. [Solving Means] A composition for a sealing member includes: 100 parts by weight of an uncrosslinked fluorine rubber component; and 0.5 to 50 (inclusive) parts by weight of a particulate resin. The particulate resin includes a compatible portion and a lubrication portion, the compatible portion having compatibility with the fluorine rubber component, the lubrication portion having lubricity with respect to the fluorine rubber component. During molding of the composition for a sealing member, crosslinking of the fluorine rubber component progresses and at least a part of the particulate resin moves to a surface due to an action of the lubrication portion. As a result, a surface layer portion including a compatible portion and a lubrication portion is formed on a surface of a molded sealing member.Type: ApplicationFiled: March 27, 2018Publication date: February 20, 2020Inventors: Shiori IRIE, Yasuhiro GUNJI, Noriaki YAMAMOTO, Hajime YANAGAWA
