PROBLEM TO BE SOLVED: To provide an ethylene-acrylic rubber composition and an ethylene acrylic rubber excellent in compressive permanent set percentage even without conducting secondary crosslinking.SOLUTION: The ethylene acrylic rubber composition contains a two-dimensional ethylene-acrylic rubber polymer consisting of ethylene and acrylic acid ester to which peroxide crosslinking is applied and hydrotalcite of 1 to 15 pts.wt. with 100 pts.wt. of the two-dimensional ethylene-acrylic rubber polymer. An ethylene acrylic rubber is manufactured by peroxide crosslinking the ethylene acrylic rubber composition by a primary crosslinking.SELECTED DRAWING: None |
