Carbon black is the result of the controlled combustion of either oil or gas. During the combustion, the unburnt char forms an extremely fine and fluffy powder known as carbon black.
Carbon black is used as a reinforcing agent in many rubber compounds which are used to manufacture many consumer products that are now part of everyday life. Carbon black makes these products more durable and resistant. It is used in tires, computers, cell phones, car parts, roof shingles, asphalt, rubber hoses, conveyor belts and many many more.
Another use of carbon black is as a colorant in paints, inks and masterbatches for plastics, just to name a few. Basically, everything that is black has a form of carbon black in it.
