6, and curves G to ■ correspond to Comparative Examples 1 to 3. Curve J represents a conventional anti-vibration rubber product whose main component is polybornene rubber. As is clear from the comparison between curves A-F and curves G~■, the peak of the loss coefficient is formed near room temperature in the temperature-loss coefficient curve for the actual product, which results in good performance in the room temperature range. It can be seen that the anti-vibration performance is demonstrated. That is, Comparative Examples 1 to
In No. 3, the peak of the loss coefficient is formed around −10 to 0° C., and vibration damping performance is exhibited only in the low temperature region. Furthermore, even when comparing Examples 1 to 5 with the conventional separate product (curve J), the peak of the loss coefficient is formed near room temperature in both cases. It can be seen that the anti-vibration performance is comparable to that of the above.
