Abstract
A fluororubber composition including a fluororubber having an iodine content of 10 to 90 mol % for the total mole of the polymer end groups and a carbon black (B), wherein a difference (δG'), represented by G′(1%)-G′(100%), is not lower than 120 kPa and not higher than 3,000 kPa, where G′(1%) denotes a shear modulus at a dynamic strain of 1% under an uncrosslinked state and G′(100%) denotes a shear modulus at a dynamic strain of 100% under an uncrosslinked state, and G′(1%) and G′(100%) are determined by a dynamic viscoelasticity test with a rubber process analyzer (RPA) in a condition that the measurement frequency is 1 Hz and the measurement temperature is 100° C.
