Carbon black [C.A.S. NO. 1333-86-4] is virtually pure elemental carbon in the form of colloidal particles that are produced by incomplete combustion or thermal decomposition of gaseous or liquid hydrocarbons under controlled conditions. Its physical appearance is that of a black, finely divided pellet or powder. Its use in tires, rubber and plastic products, printing inks and coatings is related to properties of specific surface area, particle size and structure, conductivity and color. Carbon black is also in the top 50 industrial chemicals manufactured worldwide, based on annual tonnage.
Carbon blacks are a group of intensely black submicron size pigments, composed of essentially pure carbon and made by the darkest and most finely divided materials known. Chemically, carbon black composition of hydrocarbons in an open diffusion flame, in a partial combustion chamber, or in a thermal decomposition chamber in absence of air. Carbon blacks are used as pigments, filtration aids, reinforcing agents for rubbers and the like, and for many other uses.

Hard/Soft carbon black:
Two types of carbon black are commonly used by the rubber industry for reinforcing rubber. The first is the so-called hard carbon black which imparts high wear resistance to rubber into which it has been compounded. Hard carbon black is generally used to make vehicular tire treads. Another type of carbon black, which imparts a different set of properties to rubber, is a so-called "soft" carbon black. Soft carbon blacks are generally used to reinforce rubber where a great deal of flexing is expected to be encountered, such as in tire carcasses. Hard carbon blacks are commonly classified as being in the N100, N200, or N300 series. Some carbon blacks are commonly classified as being in the N500, N600, and N700 series. The processes for making soft and hard carbon blacks differ considerably.
