Seal Member

摘要

A seal member is made of a composite material. The composite material includes: any one of an acrylic elastomer, a hydrogenated nitrile elastomer, a fluorinated elastomer, and a fluorosilicone elastomer as a main component; and a particulate filler and a fibrous filler. The particulate filler has a mean particle diameter of 1.0 μm or more and 50 μm or less. The fibrous filler has a mean diameter of 5.0 μm or more and 20 μm or less and has a mean length of 0.1 mm or more and 8 mm or less. Content of the particulate filler is 10% by volume or more and 35% by volume or less, and content of the fibrous filler is 5% by volume or more and 15% by volume or less.
