Description

Hydroxyl- And 4-Sulfophenyl-Modified Carbon Black. Sodium Salts is a specialty, surface-functionalized carbon black derivative designed for enhanced dispersion and compatibility in aqueous and polar systems. This chemical modification introduces hydrophilic functional groups, transforming the typically hydrophobic carbon black into a versatile material for advanced formulations. It is essential for industries requiring stable, high-performance black pigments or conductive additives with improved processability and final product properties.

Application

• Advanced Pigments and Inks: As a key component in high-quality aqueous inks, jet inks, and coatings, providing excellent jetting stability, color strength, and adhesion on various substrates.
• Conductive Polymers and Composites: Serving as a functional filler to impart electrical conductivity in antistatic films, EMI shielding materials, and battery electrodes while improving dispersion in polymer matrices.
• Specialty Coatings: Used in automotive, industrial, and decorative coatings where deep black color, UV stability, and corrosion resistance are critical performance factors.
• Rubber and Elastomer Reinforcement: Enhancing the mechanical properties, wear resistance, and conductivity of specialty rubber products like seals, belts, and rollers.
• Plastics and Masterbatches: Providing consistent jet-black coloration and conductivity in engineering plastics and color concentrates for electronics and automotive parts.
• Research and Development: Acting as a modified nanomaterial platform for developing novel sensors, catalysts, and energy storage devices in academic and industrial R&D settings.
