High electrical conductivity waterborne dispersions of carbon black
Carbon blacks of the same particle morphology may vary considerably in their ease of dispersion. Such differences in dispersibility can be attributed to the amount of chemisorbed complexes which, in turn, depends on the manufacturing method and on the raw materials used [33, 34].It is known that the oxygen on the surface of a carbon black particle influences the …

The Dispersion of Carbon Black in Rubber Part III. The Effect …
Abstract. The Part I of this series described a rapid method for determining the quality of carbon-black dispersion. The second paper (Part II) was concerned with the kinetics of the dispersion of carbon black into natural rubber (dispersion quality as a function of mixing time) in an internal mixer. In this paper we consider the effects of changes in dispersion quality on …
