Acetylene Black vs. Carbon Black: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on December 28, 2023
Acetylene black is a highly pure form of carbon black produced from acetylene gas, known for high conductivity and thermal stability; carbon black is a common form of carbon with a lower purity, used mainly as a pigment and reinforcing agent.

Key Differences

Acetylene black is produced by the thermal decomposition of acetylene gas, resulting in a carbon black with higher purity and unique physical properties. Carbon black, on the other hand, is typically produced by the incomplete combustion of heavy petroleum products.
Acetylene black is characterized by its high electrical conductivity and thermal stability, making it suitable for specialized applications like batteries and conductive polymers. Carbon black is less conductive but provides excellent UV protection and reinforcement properties in rubber and plastics.
Due to its high purity and conductivity, acetylene black is preferred in electrical applications, such as battery electrodes and conductors. Carbon black is widely used in the manufacturing of tires, rubber products, and as a pigment in inks, coatings, and plastics.
Acetylene black, being a specialty product, is less readily available and more expensive compared to the widely used and more affordable carbon black.
The production of acetylene black is more energy-intensive, which might contribute to a higher environmental impact. Carbon black production, while more common, also raises environmental concerns due to emissions from the combustion process.
