Carbon black

Carbon black (CAS 1333-86-4) is a fine carbon particulate produced through controlled combustion or thermal decomposition of hydrocarbons. Also marketed as furnace black, lamp black, and thermal black depending on production method.

Where is Carbon black used?

• Rubber and tires: reinforcing agent that improves abrasion resistance in elastomer matrices
• Plastics: UV stabilizer and black colorant in pipe, film, and automotive components
• Printing inks and coatings: particle-size grades for deep black pigmentation and controlled rheology
• Sealants and adhesives: modifier of surface wetting, cohesive strength, and conductivity
• It also serves as a pigment and UV stabilizer in coating systems.

Good to know: Grades are differentiated by particle size, structure, and surface area, commonly designated under ASTM classifications such as N220, N330, and N550. Specialty grades meeting food-contact or regulatory standards, including E153 classification in certain markets, are available.
