Carbon Black

material produced by the incomplete combustion of heavy petroleum products such as FCC tar, coal tar, ethylene cracking tar, with the addition of a small amount of vegetable oil.[citation needed] 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.

Carbon black uses

1. Rubber reinforcement

Carbon black is a rubber-reinforcing additive used in a multitude of rubber products. In particular, in case of vehicles, large amounts of carbon black are used for tires. In addition, carbon black is used with rubber to dampen earthquake vibration, in the soles of shoes and in many other products.

2. Colors and pigments for plastics

Compared with other colorants, carbon black has a high coloring power. Therefore. it is used as ink for printing newspapers, as ink-jet toner, and other such uses. It is also suitable as a pigment for heat-molded plastics, car fenders, coating for electric wires and other products.

3. Electric equipment and conductive components

Since carbon black has excellent conductive properties, it is used as a component for magnetic tapes and semiconductors.
