Carbon black is a fine, high-purity black powder produced by the controlled combustion of hydrocarbons. In composite applications, it serves two primary functions: as an intense black pigment for color-matched carbon fiber parts, and as a conductive additive for static dissipation and electromagnetic interference (EMI) shielding. It disperses easily into epoxy, polyester, vinyl ester, and polyurethane resin systems without significantly affecting mechanical properties at typical usage levels.
