Chemicals

Our chemical plants are located on the same sites as our refineries, where they can readily obtain refinery-produced feedstocks for their manufacturing operations. The synergy generated by the integration of our chemical and refining operations enables TonenGeneral Sekiyu and Tonen Chemical to maintain strong cost competitiveness in the chemicals market.

Quality chemicals are indispensable for end products used in every aspect of our lives, from automotive products to cosmetics. We contribute to society as a whole by providing a stable supply of quality chemicals not only to the domestic market but also to the rapidly growing Asian market.

With our competitive edge based on synergy with petroleum refining, we provide both the domestic and regional markets with a stable supply of olefins (ethylene, propylene, butadiene, etc.), which are the building blocks of chemical materials used in aircraft and automobile parts, electric and electronic components, food packaging and household items, as well as aromatics (paraxylene, ortho-xylene, benzene, etc.) used as components in polyester fiber, PET bottles and nylon fiber.

We manufacture and sell both hydrogenated and non-hydrogenated petroleum resins. Our products, with excellent cold resistance, heat stability, adhesiveness, transparency and gas barrier properties, demonstrate high functionality that meets the needs of our customers. Our products are used for a wide range of applications including industrial adhesives, high-performance tapes, fuel-efficient tires and disposable diapers. Demand is expected to increase significantly, especially in developing countries.

Methyl ethyl ketone, a highly soluble and functional chemical, is used for a number of applications in diverse fields, ranging from solvents for paint and printing ink and resin treatment for electronic components to film molding for optical panels and chemical process solvents. Hydrocarbon solvent, which is manufactured in the petroleum refining facilities, is added to car paint, agricultural chemicals, metalworking oil and other products. Such specialty chemicals work behind the scenes to enhance the convenience of our lives.
