The complicated nature of the viscoelastic properties of compounds arises from three contributions. The first is the matrix rubber the second is the carbon black, with its structure, spatial arrangement and self-interaction, and the third is the interaction between the rubber and the carbon black, including the bound rubber [15]. These three contributions each have a different temperature dependence and a different response to deformation.
