Basic Materials Business Sector

日本語 English

Basic Chemicals Business Sector handles the global manufacture and sales of phenols, acetone, bisphenol A, terephthalic acid, PET resin, industrial chemicals, and polyurethane materials.
These products are used in a wide range of areas such as engineering plastics and cushions for automobile, planes, and home appliances, clothing fiber, food and beverage containers, environmental protection such as purification of water and gases, and raw material used in the manufacturing processes of semiconductors and LCDs.

Business Vision

Mission and Vision of the Basic Materials Business Sector
In the Basic Materials Business Sector, Mitsui Chemicals provides materials across such wide-ranging fields as automobiles, housing, consumer electronics, infrastructure, and food packaging. Every effort is being made to forge a presence in Asia and to secure stable profits by providing distinctive technologies and high value-added products while further reinforcing cost competitiveness.
 Over the past several years, the Basic Materials Business Sector has undertaken a major restructuring of its activities, including substantial cutbacks in production capacity. At the same time, positive steps are being taken to substantially improve our earnings structure by restructuring the bulk and commodity product business, which is a key target under the 2014 Mid-Term Business Plan.
Minimize the Downward Profit Risk by Business Structure Improvement
Moreover, we are working diligently to improve the operational stability and profitability of ethylene, a basic raw material for petrochemical products. Specifically, we are expanding sales of EVOLUE™, a core product in our high-value-added polymer lineup.
 Despite the cloud of uncertainty that continues to hover over petrochemicals supply and demand from 2018, we adhere strictly to a policy of rationalization, make every effort to add value to our derivatives lineup, and maintain high run rates in line with the growing trend toward local production for local consumption. As a result, we will put in place a stable earnings platform that is resilient to changes in the external environment, including shifts in market conditions and the balance between supply and demand.

Aiming for Medium- and Long-Term Growth

Growing Toward 2025

Despite a delay, the impact of the expansion of facilities for polyethylene and other production derived from shale gas and Chinese coal chemicals is expected to be felt in Asia from 2018. We will look to build a Basic Materials business that has a strong presence in the Asian market by reinforcing our cost competitiveness and shifting to high-value-added products

In the petrochemical feedstock business, energies will be channeled toward further reinforcing the cost competitiveness of
naphtha cracker operations by ensuring full sales on full production capacity and the stable procurement of raw materials at low prices. In the polyolefin business, we will secure stable profits while at the same time considering the implementation of a scrap and build policy with respect to small-scale and obsolete facilities in Japan.
 By promoting sales of EVOLUE™, we intend to capture a share of demand in the highly functional sealant field, which is projected to enjoy rapid growth in the Asian market. At the same time, we will step up the utilization rate at our plant in Singapore, which has an annual capacity of 300,000 tons. Meanwhile, we will look to create new demand by addressing increasingly differentiated needs through bases in Japan. Among a host of initiatives, we will continue to promote the development of the metallocene long-chain branching-type PE, EVOLUE™ E, a next-generation product that is easy to process while remaining exceptionally strong.

Basic Chemicals
In the basic chemicals business, we will maintain our focus on stabilizing earnings. To this end, we will establish full sales and full run rates through local production for local consumption, promote thoroughgoing rationalization, and strengthen derivatives.

In the polyurethanes business, we will accelerate the pace of global business development focusing mainly on the systems business of Mitsui Chemicals & SKC Polyurethane. In addition to utilizing existing bases, we will consider setting up new production bases for the system house business.
