(57) [Summary] [Structure] (a) Fluorine-based elastomer having a specific molecular weight distribution, (b) vulcanizing agent, (c) general formula RaNHb (R Is an alkyl group having 12 to 22 carbon atoms, a is 1 to 3 and b is 3 -A fluoroelastomer composition comprising an amine compound represented by a). [Effect] The fluoroelastomer composition of the present invention containing a fluoroelastomer having a specific molecular weight distribution, a vulcanizing agent, and a specific aliphatic amine compound is as excellent as a conventionally known fluoroelastomer vulcanizate. In addition to having excellent tensile properties, heat resistance, oil resistance, sealing properties at high temperatures, etc., it also has excellent extrusion processability and roll adhesiveness, and also has excellent process formability without sticking to the extruder screw. . |
