The present invention provides a resin composition used for producing an acoustic member, the resin composition comprising: a thermosetting resin; and two or more types of particles dispersed in the thermosetting resin, the two or more types of particles comprising: heavy particles that have a higher density than the thermosetting resin and are particles other than metal particles; and light particles that have a lower density than the thermosetting resin, and the total content of the heavy particles and the light particles relative to the entire volume of a cured product of the resin composition being 10 vol % or more.

A fluoroelastomer mixture is provided with a fluoroelastomer that contains at least approximately 50 parts by weight of the fluoroelastomer mixture and further contains one or more mineral fillers in an amount of approximately 2 parts by weight to approximately 80 parts by weight per 100 parts by weight of the fluoroelastomer. The amine-resistant fluoroelastomer is a copolymer of 1,1-difluoroethylene and 2,3,3,3-tetrafluoropropene or a terpolymer of ethylene, tetrafluoroethylene, and perfluoro(methyl vinyl ether). The mineral fillers improve abrasion and/or wear properties of the fluoroelastomer mixture. A seal is provided with the fluoroelastomer mixture. A shaft seal ring is provided that has a seal body provided with the fluoroelastomer mixture.
