(57) [Summary] [Purpose] A vibration-damping elastic body composition is applied at -30 ° C to 100 ° C. When such a wide temperature range is used, excellent vibration damping performance can be stably maintained. [Structure] A thermoplastic polyester elastomer or the like having a softening point of 100 ° C. or higher. 98% by weight, 1 to 98% by weight of rubber, 1 to 98% by weight of synthetic resin such as polyamide or polybutylene terephthalate having a glass transition point of 30 to 100 ° C., and the total of these is 100% by weight. The kneaded and molded vibration-damping elastic body composition or vibration-damping sheet is used. |
