Description

Carbon Black, Carboxy-Modified, Sodium Salts is a specialized, surface-functionalized carbon material where carboxylic acid groups have been introduced and subsequently converted to their sodium salt form. This modification significantly enhances the material's dispersibility in aqueous and polar media, making it a valuable additive for improving conductivity, UV protection, and mechanical reinforcement. It is primarily sought after by formulators in the advanced coatings, conductive polymer composites, specialty rubber, and high-performance ink industries.

Application

• Conductive Coatings and Inks: Used as a conductive filler in water-based anti-static coatings, electromagnetic interference (EMI) shielding paints, and printable electronics due to its excellent dispersion and electrical properties.
• Reinforced Elastomers: Imparts reinforcement and improved processing characteristics in specialty rubber and silicone formulations, particularly where enhanced filler-polymer interaction is required.
• UV-Stabilized Polymers: Acts as a functional pigment and UV absorber in engineering plastics and films to prevent photodegradation and extend product life.
• Battery Electrodes: Serves as a conductive additive in the slurry preparation for lithium-ion battery cathodes and anodes, improving electrode conductivity and cycle life.
• Specialty Toners and Developers: Utilized in electrophotographic processes to control triboelectric charging and improve image quality.
• Analytical Chemistry: Functions as a stationary phase modifier or adsorbent in chromatographic applications.
