Effect of Tensile Rate and Carbon Black on the Fracture of Natural Rubber and Styrene-Butadiene Rubber
… of precut NR is due to the formation of a rubber/ black network. But, reduce tensile rate can decrease the N115 content for reinforcing NR with all possible cut sizes. This is noted as a second turning point of black concentration.

Multi-Scale Physics Based Modeling of Tire Rolling Resistance Considering Aging
… our daily life. The tire's primary component is rubber, which consumes energy when it rotates on a substrate due to the viscoelastic material's internal friction: a phenomenon referred to as rolling resistance. The interaction between the tire and the road surface is one of the most intricate and …

The effect of layered double hydroxides on the vulcanisation and properties of elastomer compounds
Elastomers such as natural rubber (NR) and solution styrene butadiene rubber (SSBR) are widely used, especially in the tyre industry. These elastomers are crosslinked, most often via sulphur vulcanisation, in order to achieve the desired mechanical properties. In recent years the use of ZnO as a …
