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:
“Words like “freedom,” “justice,” “democracy” are not common concepts; on the contrary, they are rare. People are not born knowing what these are. It takes enormous and, above all, individual effort to arrive at the respect for other people that these words imply.”
—James Baldwin (1924–1987)
“They sang, but had not human tunes nor words,
Though all was done in common as before;
They had changed their throats and had the throats of birds.”
—William Butler Yeats (1865–1939)
