The present disclosure provides reinforcing filler-containing rubber compositions suitable for use in tires, and particularly in tire treads. These rubber compositions comprise a metal carboxylate. The metal carboxylate provides improved processability to the rubber compositions in the form of a reduced Mooney viscosity. In certain exemplary embodiments, these rubber compositions containing the metal carboxylate also have an enhanced elastic modulus (also referred to as the G′). Further, in certain of the enhanced elastic modulus embodiments, the rubber compositions containing the metal carboxylate also have decreased hysteresis loss.
本公开提供了适用于轮胎,特别是轮胎胎面的增强填料含有橡胶组合物。这些橡胶组合物包括金属羧酸盐。金属羧酸盐提供了改善橡胶组合物加工性的能力,以减少穆尼粘度。在某些示例实施中,这些含有金属羧酸盐的橡胶组合物还具有增强的弹性模量(也称为G')。此外,在某些增强弹性模量的实施中,含有金属羧酸盐的橡胶组合物还具有降低的滞后损失。
