PURPOSE:To provide a high-damping rubber composition for oscillation-insulating rubber having balanced characteristics such as hysteresis loss, elongation, temperature dependency of elastic modulus in practical temperature range and tensile strength. CONSTITUTION:The objective high-damping rubber composition for oscillation- insulating rubber is produced by compounding 100 pts.wt. of natural rubber with 15-45 pts.wt. of a coumarone resin having a softening point of 333-373K. |
