Profile: Cabot Supermetals is a global performance materials company. Our primary products are rubber & specialty grade carbon blacks, inkjet colorants, fumed metal oxides, aerogel, tantalum & related products, and cesium formate drilling fluids. Our carbon black is used as a reinforcing agent in tires. It can also be used as a pigmenting, UV stabilizing, and conductive agent in a variety of common & specialty products, including tire innerliners, carcasses, sidewalls & treads, as well as in industrial rubber products, like belts, hoses & gaskets. An intensely black powder, carbon black is produced by subjecting heavy residual oil feedstock to extremely high temperatures in a carefully controlled combustion process. We manufacture dozens of commercial grades of varying size and structure, each produced through minute adjustments in different reactors.
