Abstract
The invention provides a fluoroelastomer composition capable of providing a molded article that is inexpensive and has excellent heat-aging resistance. The fluoroelastomer composition is a peroxide-crosslinkable fluoroelastomer composition containing a fluorine-containing elastomer that contains 25 to 90 mol % of a unit of vinylidene fluoride, 10 to 75 mol % of a unit of a fluorine-containing monomer other than the vinylidene fluoride, 0 to 10 mol % of a unit of a fluorine-free monomer copolymerizable with the vinylidene fluoride, and 0.1% by mass or less of an iodine atom and a bromine atom; an organic peroxide having a specific structure; and a co-crosslinking agent. The organic peroxide is present in an amount of 0.3 to 10 parts by mass relative to 100 parts by mass of the fluorine-containing elastomer.
