Potential of Sumilink-200 was investigated in a typical natural rubber-based tread compound in connection with its ability to act as a coupling agent for carbon black to reduce hysteresis loss of the compound. Optimum physical properties were obtained at 2 phr loading of Sumilink-200. At this loading, tensile modulus at 300% elongation improved by 9.6% with a reduction in visco-elastic energy dissipation (loss tangent) at 60°C by 8.3% over the control compound. The abrasion resistance properties of the compounds found to remain unaffected with the introduction of Sumilink-200.

通过使用新型偶联剂改善典型的炭黑填充天然橡胶胎面胶的磁滞

研究了Sumilink-200在典型的天然橡胶基胎面胶中的潜力及其与炭黑偶联剂的作用，以减少该胶的磁滞损耗。在2 phr的Sumilink-200负载下可获得最佳的物理性能。在该载荷下，与对照化合物相比，在300％伸长率下的拉伸模量提高了9.6％，而在60°C时的粘弹能量耗散（损耗角正切）降低了8.3％。发现这些化合物的耐磨性不会因引入Sumilink-200而受到影响。
