Usages: 

1.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.

2.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.
