Features Of Cabot N550 Spheron SO Carbon Black

  1. Optimized spherical morphology for enhanced dispersion in rubber and polymer matrices.

  2. Surface-oxidized (SO) treatment improves compatibility with polar polymers and aqueous systems.

  3. Consistent particle size distribution ensures reproducible reinforcement and conductivity performance.

  4. Low abrasion characteristics support extended processing life and reduced equipment wear.

  5. High structure level provides excellent filler network formation for improved tensile strength and modulus.

Typical Applications Of Cabot N550 Spheron SO Carbon Black

  1. Tire treads and sidewalls requiring balanced wear resistance and rolling resistance.

  2. Industrial rubber goods including conveyor belts, hoses, and vibration dampers.

  3. Conductive masterbatches for antistatic and electrostatic discharge (ESD) applications.

  4. Polyolefin and thermoplastic elastomer (TPE) compounds for automotive interior components.

  5. Specialty coatings and inks where uniform blackness and rheological control are critical.
