Highly-conductive carbon blacks and conductive concentrates for plastics

Cabot Corporation has launched the Vulcan XCmax family of super conductive carbon blacks for use in plastics applications in which high conductivity at low carbon black loadings is required, e. g. for wire and cable, antistatic flooring and safety systems, automotive fuel tanks and inlets, coatings, and electronics and electrical products.

The new products are designed for applications that require plastics to be conductive or dissipative at relatively low carbon black loadings. This ensures the mechanical properties of the underlying polymer are not affected, which is key for many electrostatic dissipation applications. The Vulcan XCmax family complements the company’s existing XC conductive carbon blacks.

In addition, Cabot has introduced a new line of conductive concentrates to complement its existing Cabelec conductive compounds products. According to the company, the new products, Cabelec CC6135 polystyrene concentrate and Cabelec CC6277 polyethylene concentrate, enable converters greater control of formulations to reach application-specific resistivity targets.

The use of the new conductive concentrates in place of a finished compound allows formulators to add proprietary polymers and additive packages to tailor a range of compounds to meet specific customer needs. This range of conductive concentrates will be expanded to include a wider range of polymer carriers, says Cabot.
