Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of heavy petroleum products such as FCC tar, coal tar, or ethylene cracking tar. Carbon black is a form of paracrystalline carbon that has a high surface-area-to-volume ratio, albeit lower than that of activated carbon. It is dissimilar to soot in its much higher surface-area-to-volume ratio and significantly lower (negligible and non-bioavailable) PAH (polycyclic aromatic hydrocarbon)content.
However, carbon black is widely used as a model compound for diesel soot for diesel oxidation experiments. Carbon black is mainly used as a reinforcing filler in tires and other rubber products. In plastics, paints, and inks, carbon black is used as a color pigment.

Thermax® N990 medium thermal carbon black is a unique carbon characterized by the largest particle size and lowest structure available. The choice of filler for an elastomeric compound is critical decision for any compounder as cost, performance, processability, scrap rate and handling all must be considered when assessing the total quality cost of a compound. Thermax® N990 is an excellent choice for modern technologically advanced polymers. The advantage of Thermax® N990 in nitrile rubber compounds has been demonstrated. Thermax® N990 can reduce the total quality cost of nitrile compounds while improving or maintaining key dynamic properties
