Carbon black is a fine powder or bead-like material, characterized by its pure black color, produced through the incomplete combustion of carbon-rich substances, mainly petroleum. It is created via thermal decomposition or partial combustion using hydrocarbons such as oil or natural gas. The properties of carbon black depend on the production method, leading to its classification based on the manufacturing process. The main production methods include the furnace black process, channel process, acetylene black process, and lampblack process. Carbon black is insoluble in water, acids, and alkalis but can burn in air to form carbon dioxide. While its primary component is carbon, it also contains trace amounts of hydrogen, oxygen, sulfur, ash, tar, and water.
The primary application of carbon black is as a pigment and reinforcing agent in rubber products, where it strengthens and fills materials like tires, belts, tire cord layers, tread rubbers, covering rubbers, sidewalls, inner tubes, bicycle tires, rubber hoses, tapes, cables, shoes, and extruded or calendered rubber goods. Additionally, carbon black is used as a colorant in printing inks, paints, coatings, plastics, textile printing, color pastes, adhesives, and sealants, as well as in printer toner. In high-tech materials, carbon black functions as a pigment and conductive agent, finding use in antistatic films, fibers, and floppy disks.
