Carbon blacks particle size and structure

The flow of carbon black filled rubbers in the unvulcanized state is of obvious technological importance. Qualitatively, the principal effects of carbon black particle size and structure on the plasticity of... 

Particle diameters can range from less than 20 nm in some furnace grades to a few hundred nanometres in thermal blacks. A discrete rigid colloidal entity of coalesced particles is the smallest dispersible unit of CB. Carbon black particle size and structure comparison are show on Figures 6.9 and 6.10.
