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:
“How like a prodigal doth nature seem,
When thou, for all thy gold, so common art!
Thou teachest me to deem
More sacredly of every human heart,
Since each reflects in joy its scanty gleam
Of Heaven, and could some wondrous secret show,
Did we but pay the love we owe,
And with a child’s undoubting wisdom look
On all these living pages of God’s book.”
—James Russell Lowell (1819–1891)
“Read, mark, learn, and inwardly digest.”
—Book Of Common Prayer, The. The Second Sunday in Advent, “The Collect,” (1662)
