Abstract:
To provide a fluororubber molded article which is inexpensive and excellent in fuel barrier properties against an alcohol-containing fuel. A fluororubber molded article obtained by molding and crosslinking a cross-linkable composition comprising a fluoroelastomer (A) and a fluoroelastomer (B), wherein the fluoroelastomer (A) is a copolymer comprising tetrafluoroethylene units and perfluorovinyl ether units represented by CF2═CF—O—Rf (Rf is a C1-20 perfluoroalkyl group or a C2-20 perfluoroalkyl group having an etheric oxygen atom between carbon atoms), the fluoroelastomer (B) is a copolymer comprising tetrafluoroethylene units, propylene units and vinylidene fluoride units, and the mass ratio of (A)/(B) is from 99/1 to 30/70.
