Carbon Black
Physical Properties
Particle size= 13-95 nm
Chemical Properties
Nominal purity= 98.5 to 99.6%
Typical Applications
A very important filler in the rubber industry and next to titanium dioxide, the most important pigment, printing inks, toners, single-ply roofing, inks, paints and plastics.
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 (8,930,000 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 causes the material to degrade.
Carbon black from vegetable origin is used as a food coloring, in Europe known as additive E153.
Description
A black, amorphous, carbon pigment produced by the thermal decomposition of natural hydrocarbons. There are three different types (furnace, channel, and lamp black).
Carbon black is a material produced by the incomplete combustion of heavy petroleum products such as FCC tar, coal tar, ethylene cracking tar, and a small amount from vegetable oil. Carbon black is a form of amorphous carbon that has a high surface area to volume ratio, although its surface area to volume ratio is low compared to activated carbon. It is dissimilar to soot because of its much higher surface area to volume ratio and significantly less (negligible and non-bioavailable) PAH content. Carbon black is used as a pigment and reinforcement in rubber and plastic products.
