<p>Cross-linkable or cross-linked rubber composition (A), useful to form a rubber weather-strip with a non-sticky surface and a compression set in a cross linked state, comprises an elastomer and a crosslinking system comprising an organic peroxide, which comprises a first organic salt (I) (>= 2 pce) of transition metal (e.g. manganese), and a second organic salt (II) (>= 2 pce) of transition metal (e.g. zinc). Cross-linkable or cross-linked rubber composition (A), useful to form a cross linked rubber weather-strip with a non-sticky surface and a compression set, comprises an elastomer and a crosslinking system comprising an organic peroxide, which comprises a first organic salt (I) (>= 2 pce) (where pce is parts by weight for 100 parts of elastomers) of transition metal (manganese, iron, cerium or vanadium) and a second organic salt (II) (>= 2 pce) of transition metal (zinc, zirconium, lithium, calcium or barium). Independent claims are also included for: (1) the preparation of rubber composition (A); and (2) a rubber weather-strip comprising (A).</p> |
