By leveraging the competitive advantage of our domestic bases and tapping into the Asian market in added-value fields, we aim to secure stable earnings and build a framework that serves as a cornerstone business and supports the Group as a whole.

Basic Information

Mission of the Basic Materials domain

Centering on petrochemicals and basic chemicals, we provide materials in a wide range of fields in this business, such as automotive, housing, consumer electronics, infrastructure, and food packaging. We aim to forge a presence in Asia, secure stable earnings, and build a cornerstone business by providing distinctive technologies, expanding our lineup of value-added products, and further strengthening our cost competitiveness.

Business vision

We are substantially improving our earnings structure by steadily executing business restructuring. At the same time, we are working to further strengthen competitiveness of the basic raw material ethylene. We are also mounting an effort to stabilize operations and improve profitability by expanding sales of EVOLUE™ and other ethylene-based high value-added polymers.
Despite the uncertainty and volatility in the environment surrounding this business, we are striving to further deepen its operations by continuing to implement thorough cost reductions, expand our differentiated products, and maintain our high operating rate by sticking to our local production for local consumption approach. In doing so, we aim to build a stable earnings base that is resistant to changes in market prices and the supply-demand balance.
