Carbon Black XC-72
VULCAN XC72 specialty carbon black is a uniquely designed conductive carbon
black from our XC family of conductive carbon blacks. Its unique properties allow
end products to deliver functionality at relatively lower loading levels compared to
Cabot’s other carbon blacks in the XC family. VULCAN XC72 specialty carbon black has
demonstrated its performance capabilities for many years, allowing compounders
to feel confident using it in a wide range of conductive applications.
Key Applications
VULCAN XC72 specialty carbon black is suitable for use across a range of conductive
applications:
 Conductor shields used in medium voltage power cables
 Insulation shields used in medium voltage power cables
 Conductive plastic molded or extruded parts where protection from electrostatic
discharge (ESD) is required
By compounding VULCAN XC72 specialty carbon black into plastics, a compounder
can change the electrical property of the final product from insulative to conductive,
anti-static, or dissipative. For instance, VULCAN XC72 specialty carbon black is
compounded into plastics trays and pouches that are used extensively in electronics
manufacturing to protect sensitive products against electrostatic discharge. In
addition, it is frequently compounded in molded or extruded parts to help deliver
dissipative performance in hazardous environments.
Performance Features
VULCAN XC72 specialty carbon black has several important features:
 A full range of conductivity performance depending on loading (but typically at lower
loadings than other XC carbon blacks or standard carbon blacks)
 Good dispersion characteristics to promote surface smoothness and preserve
mechanical performance of polymer
 Low sulfur and grit levels
