Today, carbon black are used as a pigmenting, UV stabilizing and conductive agent in a variety of common and specialty products, including:
• Plastics: carbon blacks are now widely used for masterbatch applications, such as films, fibers, moldings, pipes and semi-conductive cables.
• Printing Inks: carbon blacks enhance formulations and deliver broad flexibility in meeting specific color requirements.Pigment Carbon Black
• Coatings: Carbon blacks provide pigmentation, conductivity and UV protection for a number of coating applications including marine, aerospace and industrial.
The coatings and inks industries prefer grades of carbon black that are acid oxidized. Acid is sprayed in high temperature dryers during the manufacturing process to change the inherent surface chemistry of the black. The amount of chemically-bonded oxygen on the surface area of the black is increased to enhance performance characteristics.
An intensely black powder, carbon black is produced by subjecting heavy residual oil feedstock to extremely high temperatures in a carefully controlled combustion process. Zaozhuang Xinyuan Chemical manufactures dozens of commercial grades of varying size and structure, each produced through minute adjustments in different reactors.
