(57) Abstract: The crosslinkable rubber composition of the present invention comprises a structural unit in which a non-conjugated polyene is derived from a specific norbornene compound having a terminal vinyl group and another specific non-conjugated polyene compound. An ethylene / α-olefin / non-conjugated polyene random copolymer rubber having a constitutional unit, a SiH group-containing compound having at least two SiH groups in one molecule, and a catalyst, a reaction inhibitor and the like as required. The automotive weather strip, hose, vibration-isolating rubber, belt, sealing material, foam, covered electric wire, electric wire joint, electric insulating part, semiconductive rubber part, OA equipment roll, industrial roll, civil engineering construction stop of the present invention Water sheets and household rubber products are composed of the above composition. [Effect] The above composition has a high crosslinking rate, is excellent in productivity of a crosslinked rubber molded article, can be crosslinked with hot air such as HAV and UHF, and has compression set resistance, strength properties, heat resistance, A crosslinked rubber molded article (including a foamed article) having excellent properties such as weather resistance, adhesion, oil resistance after deterioration, and abrasion resistance can be provided. |
