- both performances are trade-offs, if one is improved without compromising the other, both can be achieved as a result.
- a fuel-efficient tire by blending silica and it is particularly aimed at fuel-saving performance, but since the siliency has many hydrophilic groups on the surface and it is difficult to fit with rubber polymers, Silicas tend to agglomerate. In that case, when the tire is deformed during driving, silica rubs against each other to generate heat, resulting in extra energy loss. Therefore, the point is how to disperse silica in the rubber polymer.
- the petroleum-based aromatic-containing oil containing the above-mentioned specific component in a specific amount acts on the dispersion or dissolution of various compounding agents including silica, and their behavior in the rubber polymer has a favorable influence on each physical property. As a result, it is considered that the anti-performance is compatible.
