Abstract
Provided is a seal material having excellent non-adherence to metal surfaces. The seal material is formed of a cross-linked rubber that is obtained through cross-linking of a cross-linkable rubber composition containing a binary fluororubber, a carbon material, and a polyol cross-linker. The carbon material includes one or more carbon nanotubes. The cross-linked rubber has an adhesion strength of 2 N or less to a metal surface after being heated at 250° C. for 70 hours while in contact with the metal surface.
