The chain of carbon products derived from coal has been a core business since the founding of the company in 1934.  Various products are created to support domestic and overseas steel, auto, and other industries.  In addition to coke for iron-making, carbon products derived from coal tar include needle coke for electrodes, pitch coke for carbon specialities, carbon black (CB), synthetic rubber (CB master batch), and so on.

Coke“Mitsubishi™ Coke”

Mitsubishi™ Coke

Mitsubishi™ Coke is a raw material used in blast furnaces.  The coke is manufactured by blending many types of coal and carbonized (coking) at a high temperature of about 1200 ℃ in a coke oven. Coke is one of the essential raw materials for iron-making in blast furnaces, and is supplied to major steel mills in Japan and other countries.

Needle Coke“Needle Coke”

Needle Coke

Needle cokes are used as a primary material for graphite electrodes in electric furnace.
Coal-based needle coke is produced from coal tar that appears during coke production.
Compared to petroleum-based needle coke, coal-based needle coke has excellent physical properties, such as low co-efficient of thermal expansion and low electric resistance, along with less spalling and less breakage. 
CAS No.94113-91-4
