HEAT-RESISTANT RUBBER COMPOSITION AND VIBRATION-PROOF RUBBER

摘要

PROBLEM TO BE SOLVED: To provide a heat-resistant rubber composition excellent in heat resistance suitable for vibration-proof rubber used in a high temperature atmosphere such as an engine mount or a dumper pulley of automobile. SOLUTION: The heat-resistant rubber composition comprises at least one or two or more kinds selected from ethylene-propylene-diene copolymers and diene-based rubbers as rubber components, and 0.5-5 pts.wt. of one or two or more antioxidants selected from hindered amine compounds having 800-10,000 of molecular weight and hindered phenol compounds per 100 pts.wt. of rubber component.
