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.

We offer various forms of materials including UD prepreg in which carbon fibers are drawn uni-directionally and impregnated with resin and cross prepreg which is carbon-fiber-woven cloth impregnated with resin.
In particular, products using DIALEAD, that is ultra-high modulus pitch-based carbon fiber are widely used as materials essential for manufacturing of parts and components for various industrial machines represented by carbon rollers and robot hands. Other applications include sports, construction / civil engineering, and aerospace industries. The HX1 Series is a prepreg impregnated with special epoxy resin developed on the assumption of use in a high temperature range. Using this prepreg, it is possible to expand the range of applications of CFRP products.
DIALEAD is a pitch-based carbon fiber supported by many proprietary technologies as a result of coal chemistry by Mitsubishi Chemical over many years. The product is widely applied to fields such as aerospace, industry, and sports.
Mitsubishi Chemical continues to develop an ever-expanding value chain from raw materials to final product through the use of PAN-based carbon fiber and pitch-based carbon fiber.
Carbon fibers are one quarter the weight of steel but have about 10 times the strength; thereby creating a light and tough material that is stronger than conventional metal materials. Carbon fibers have a variety of features that include being electrically conductive, strongly wear-resistant, and transparent to X-rays. They are mainly used in composite materials in combination with plastics. Mitsubishi Chemical's carbon fibers have obtained the Japan Industrial Standard of quality management system for the aerospace and defense industry (JIS Q 9100), and we are continuing to raise our quality control levels further still.
PYROFIL™ carbon fiber and its composites, are advanced high-performance materials born from technology centered on synthetic high polymer chemistry, in which Mitsubishi Chemical excels. We have an integrated framework for production that includes polymerization of acrylonitrile (PAN), spinning of PAN fiber (precursor),carbonization of a precursor (carbon fiber), weaving, prepregging, and chopping of carbon fiber.
We manufacture high-performance and high-quality carbon golf shafts utilizing our consistent production process that starts from the carbon material. Our shafts are used by an overwhelmingly large percentage of the world's top players and are there during great moments in golf history. Such is the testament of the performance of these shafts. We develop and provide many different products that are ideal for not only professional golfers but also casual golfers, senior golfers, and female golfers.
CARBOLEADER is a carbon roller simultaneously realizing lightweight, high stiffness and a high critical number of revolutions. The product is used in a comprehensive range of fields including LCDs, film manufacturing, printing, and papermaking and substantially contributes to improve production quality, acceleration of production speed, and productivity improvement by reduced defect rates and cost reduction.
DIALEAD composite is a carbon fiber composite material compressed by resin. The formal name is carbon fiber reinforced plastics or CFRP. Taking advantage of excellent properties not available from conventional metals and ceramics, the product is widely used in various applications.
Pyrofil pellets are a thermoplastic molding material that is made from blending our PAN-based carbon figure Pyrofil product with our pitch-based carbon fiber Dialead with various resins to achieve performance better than typical reinforced resins.
We carefully select the base resin and carbon fiber materials in accordance with specific applications to provide products of the highest quality unmatched in the industry.
