Common Uses
The most common use (70%) of carbon black is as a pigment and reinforcing phase in automobile tires. Carbon black also helps conduct heat away from the tread and belt area of the tire, reducing thermal damage and increasing tire life. Carbon black particles are also employed in some radar absorbent materials and in photocopier and laser printer toner.
Total production was around 8,100,000 metric tons (8,900,000 short tons) in 2006. About 20% of world production goes into belts, hoses, and other non-tire rubber goods. The balance is mainly used as a pigment in inks, coatings and plastics. For example, it is added to polypropylene because it absorbs ultraviolet radiation, which otherwise causes the material to degrade.
Carbon black from vegetable origin is used as a food coloring, in Europe known as additive E152. It is approved for use as additive 153(Carbon blacks or Vegetable carbon) in Australia and New Zealand but has been banned in the USA.

Famous quotes containing the word common:
“There is something antique, even, in his style of treating his subject, reminding us that Heroes and Demi-gods, Fates and Furies, still exist; the common man is nothing to him, but after death the hero is apotheosized and has a place in heaven, as in the religion of the Greeks.”
—Henry David Thoreau (1817–1862)
“Romance reading and writing might be seen ... as a collectively elaborated female ritual through which women explore the consequences of their common social condition as the appendages of men and attempt to imagine a more perfect state where all the needs they so intensely feel and accept as given would be adequately addressed.”
—Janice A. Radway (b. 1949)
