Carbon black Properties

Carbon black



Carbon black is a material produced by the incomplete combustion of heavy petroleum products such as FCC tar, coal tar, ethylene cracking tar, and a small amount from vegetable oil. Carbon black is a form of amorphous carbon that has a high surface-area-to-volume ratio, although its surface-area-to-volume ratio is low compared to that of activated carbon. It is dissimilar to soot in its much higher surface-area-to-volume ratio and significantly less PAH (polycyclic aromatic hydrocarbon) content. Carbon black is used as a pigment and reinforcement in rubber and plastic products.
