Abstract: Provided is a fluororubber composition capable of providing a crosslinked fluororubber article that exhibits not only heat resistance, but also excellent mechanical properties at high temperatures. The fluororubber composition includes a fluororubber (A), a carbon black (B), and an aromatic petroleum resin (E), and the fluororubber composition has a difference δG′ (G′ (1%)−G′ (100%)) of 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%, G′ (100%) denotes a shear modulus at a dynamic strain of 100%, and G′ (1%) and G′ (100%) are determined by a dynamic viscoelasticity test carried out on an unvulcanised rubber with a rubber process analyzer (RPA) in a condition that the measurement frequency is 1 Hz and the measurement temperature is 100° C.

Abstract: There is provided a polyol-crosslinkable fluorine-containing elastomer composition which is excellent in chemical resistance, solvent resistance (especially resistance to an acidic solvent) and fuel resistance (especially biofuel resistance) and is crosslinkable at the same crosslinking speed as in the case of using calcium hydroxide in a usual amount even without blending calcium hydroxide (or decreasing a blending amount of calcium hydroxide). The fluorine-containing elastomer composition comprises a polyol-crosslinkable fluorine-containing elastomer, a polyol crosslinking agent and a silicate of an alkali metal.
