Abstract
The aim of this work was to study the properties of carbon black CH85 of the OMCARB series and to compare them with the properties of standard carbon blacks N339 and N234. The morphological characteristics, the size distribution of the globules and aggregates, the surface area, the proportion of micropore area, the degree of branching of aggregates, and also the mechanical and chemical properties were measured and calculated. The average size of the aggregates of CH85 is greater than that of N339 and N234, and the aggregates have a more open and branched structure. The iodine adsorption by CH85 is practically the same as that by N339 and lower than that by N234. The low-hysteresis index calculated on the basis of structural data is much better for CH85. This opens up the possibility of using this type of carbon black for the development of elastomeric materials with low hysteresis.
