Abstract
To provide a sealing material which is excellent in sealability under high-temperature conditions as well as crack resistance at high temperatures and high compression. A sealing material comprising a cross-linked fluororubber layer obtainable by cross-linking a fluororubber composition containing a fluororubber (A) and a carbon black (B), the cross-linked fluororubber layer having a loss modulus E″ of 600 kPa or higher and 6,000 kPa or lower determined by a dynamic viscoelasticity test under conditions of measurement temperature: 160° C., tensile strain: 1%, initial force: 157 cN, and frequency: 10 Hz.
