Carbon black is a form of carbon powder used as an additive to reinforce the wear resistance of rubber materials, or to add properties such as a black pigment to polymer blends.

Black Bear Carbon’s carbon black is produced from worn-out tires.

When carbon black is used in elastomers (rubber), it gives the material increased stiffness and UV protection. It also contributes to better abrasion resistance and fatigue strength.

Carbon black is one of the most common fillers and is available in different particle sizes, with different surface structures on the particles. The particle size affects the material by changing its physical properties and increasing its settling characteristics.

Common applications of carbon black include use as an additive in rubber compounds for automotive tires, printing or paint, technical rubber, and as a pigment in plastics.
