The strain amplitude dependence of the viscoelastic properties of eight different carbon blacks dispersed in two different rubbery networks is investigated and evaluated within the Cole‐Cole approach for the complex elastic modulus at fixed temperature and frequency. This approach is based on the Kraus model of strain‐dependent filler agglomeration‐deagglomeration rates. We find a non‐integer universal shape exponent of the Cole‐Cole process that obviously depends only on the surrounding polymer matrix but is independent of the filler grade. The exponent can be related to the fractal dimension of the carbon black surface.
