Charcoal Series

SEAST is a rubber-grade carbon black produced by TOKAI CARBON. When added to rubber, it enhances strength and wear resistance. Widely used in tires and industrial rubber components, SEAST has earned strong recognition in Japan's furnace carbon black market for its reliable quality. TOKAI CARBON continues to drive R&D for electric vehicles and advanced tire technologies to meet evolving market and customer needs.

TOKABLACK is a coloring and conductive carbon black developed in-house by TOKAI CARBON, leveraging the expertise gained from SEAST. It is widely used in newspaper and printing inks, plastic coloration, and antistatic applications such as OA rollers for laser printers. Notably recognized for its performance as a semiconductive material between wire conductors and insulators, it supports comfortable daily life as a critical component of essential infrastructure.

AQUA-BLACK uses a proprietary surface treatment to make carbon black, normally incompatible with water, hydrophilic. It significantly improves self-dispersion in water without requiring dispersing aids. As a black ink material for inkjet printers, it delivers the deep, rich color characteristic of carbon black. Through this innovative carbon black development, TOKAI CARBON has entered a new market with growing demand and strong growth potential.
