Abstract
An NBR composition for rubber laminated metal having 1 to 3 parts by weight of sulfur and 1 to 15 parts by weight of a disulfide compound such as 4,4'-dithiodimorpholine or dithiodicaprolactam represented by the general formula RN—S—S—NR (wherein RN is a cyclic linking group formed together with the N atom bonded to the S atom), based on 100 parts by weight of NBR. The rubber composition that can improve the protrusion properties of a rubber layer when used for, for example, a gasket or a brake shim material that is a laminated composite metal laminated with another metal plate.
