Boosting production capacity for many of the Group’s products in the next business term is essential to translate current demand growth into business opportunities. Accordingly, the Mitsui Chemicals Group will steadily increase its production capacity in line with its business plan for each product. In addition to expanding and reinforcing existing businesses, energies will be channeled toward promoting the Mobility strategy across the Group as a whole. Moving forward, every effort will be made to strengthen the Group’s ability to provide its customers with optimal solutions.

Growth Strategies
  • Continually introduce new differentiated products and boost production capacity as part of ongoing expansion efforts focused on existing businesses.
  • Work to enhance our product portfolio in the mobility business by bolstering our customer support, establishing technology for fiber-reinforced composite materials, and facilitating the switch to multi-material solutions.
  • Foster open innovation and collaboration to anticipate customer needs with the aim of promoting new business development in new markets and facilitating a shift toward downstream businesses and services.
Investment Strategies
  • As for our polymer product lines, which require large-scale production facilities, we will continue working to bolster our competitive advantage by quickly boosting production capacity in optimal locations to meet growing global demand.
  • As for our compound products, we will continue to strengthen our global supply system, which is designed to best meet customer needs, by boosting production capacity in locations where the products are manufactured and consumed.
Fiscal 2018 Plan

By capturing growth in ICT-related markets and increasing automobile production we expect to expand sales of major products. Despite such risks as rising raw material prices, earnings are expected to continue on the previous year’s upward trend in fiscal 2018, boosted by higher sales. We plan also to raise production capacity at existing businesses to keep up with expanding demand. In addition, we will strengthen our global supply network. Furthermore, we will promote new business creation and accelerate new product development as we work to implement mobility business strategies aiming for long-term growth.

TOPICS - Aiming to Become the World Leader
Fuelling Further PP Compound Business Expansion

The Mitsui Chemicals Group’s automotive material PP compound business ranks second globally and first in Asia. The Group has also built a solid track record in North America and holds an approximately 30% share of the U.S. automobile manufacturing sector. PP compounds combine polypropylene with other polymers and additional agents to achieve functionality and performance that polypropylene alone is unable to provide. Leveraging its proven expertise in material design technologies in combination with proprietary resins, the Mitsui Chemicals Group is providing highly acclaimed high-quality PP compounds that address various customer needs. Moreover, the Group is building a structure that is finely attuned to the global strategies of automobile manufacturers. In a bid to address customer needs in a timely manner, the Group currently maintains eight production sites and five R&D bases worldwide. We recently established a new production base in the Netherlands—our first in Europe—as we expect business to expand in Europe. Commercial operation is slated to begin in fiscal 2020. The Group is progressively increasing production capacity in line with growing demand and its efforts to increase its market share. Moving forward, every effort will be made to identify markets that exhibit continued growth and to further reinforce Group operations.

Aim for production capacity of 1,080Kt/year in FY2020
