Tyre recycler Scandinavian Enviro Systems says it has developed a new type of recovered carbon black with improved dispersion properties. The new type of carbon black has been developed to meet demand from the tyre and rubber industry, it adds.
The new type of carbon black has been produced for some time at Enviro’s plant in Åsensbruk, Sweden, and has acquired properties enhancing its interaction with other chemicals and ingredients when manufacturing tyres and rubber parts, for example. Thanks to the improved dispersion of the new type of recovered carbon black, end products such as rubber, tyres, plastics and pigments can potentially be produced with a more consistent and better outcome, the firm claims.
In the long run, this improvement could result in that the new type of recovered carbon black can replace a larger amount of virgin carbon black (higher degree of substitution) in a number of applications.
The new type of carbon black is aimed at customers and applications where recovered carbon black with improved dispersion properties can contribute to improved performance for the rubber compound.
According to the ISCC certification obtained by Enviro, the use of the company’s recovered carbon black will lead to a reduction in carbon emissions of up to 93%, compared with the use of the corresponding amount of virgin carbon black.
