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 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.
Pitch coke is produced from coal tar that appears during coke production.
Pitch cokes are an essential raw material for building production equipment for semiconductor or solar array panel.
It is also used as a raw material for the anode in aluminum smelting.
DIAPOL™-WMB is a composite material (wet masterbatch) produced by acid coagulation of SBR latex, carbon black and water slurry in an ultradispersion process. It is widely applied as a raw material for industrial products; water seals and gaskets; and tires and belts.
MITSUBISHI™ Carbon Black is a black pigment that has been used in a wide range of fields such as newspaper ink, printing ink, colored resin, paint, toner, colored paper, India ink, and ceramics.
Various grades of carbon blacks are available ranging from all- purpose grade to high-grade. In addition, our line of products includes industrial and environmentally-friendly carbon blacks.
