Aiming for Medium- and Long-Term Growth

Growing Toward 2025

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.


The Mitsui Chemicals Group is evaluating the need to increase production capacity for both TAFMER™ and LUCANT™, which are growing globally. Led by its EPT business activities, the Group is also looking to steadily expand high-value-added businesses by introducing new differentiated products. In this regard, the Group will focus on both quantitative and qualitative expansion.

Performance Compounds

The Mitsui Chemicals Group will promptly boost production capacity to fully capture growing global demand for ADMER™ and MILASTOMER™, over the medium to long term. In addition, the Group will realize steady profit from investment in increasing production capacity in China and Japan.

Overseas PP Compounds

In FY2017, the Mitsui Chemicals Group will increase its production capacity in North America, Mexico, and India in light of the forecast upswing in demand and ensure that these investments lead to stable profit. The Group will assess the potential of establishing a direct production base in Europe as a part of efforts to strengthen its global business structure.

Performance Polymers

APEL™ enjoys a strong reputation in the optical lens application market and offers excellent optical characteristics and heat resistance. Efforts are under way to promote its use in automotive camera lenses, which are currently primarily glass. Precisely identifying growth opportunities in the ICT market, the Group will also take concrete steps to reinforce its production framework for each product.

Providing New Products and Total Solutions

In FY2016, the Mitsui Chemicals Group completed plants at a joint venture company in China and its Nagoya Factory to produce electrolyte solutions for LIBs, which are expected to see strong demand growth going forward. We are working to quickly commercialize such products and technologies as the metal resin integral technology POLYMETAC™ as well as STOBA™, which helps to prevent LIB thermal runaway as we seek to meet customer needs with a broad-ranging product lineup.
The Group also established the Mobility Development Center, a test center for introducing plastic materials for automotive parts and molding technologies for such materials, based on the outstanding mold technologies of Kyowa Industrial Co., Ltd. which was acquired in 2014. By combining diverse materials, such as plastic compounds, and composite materials as well as molding technologies, we will put forward practical total solutions to better address customer needs.

We will realize customer and consumer value with solutions based on the actual forms and therefore closer to the customers’ needs for materials,
parts and mold technology that our Group possesses.

TOPICS - Aiming to Become the World Leader in PP Compounds

The Mitsui Chemicals Group’s automotive material PP compound business ranks second globally and first in Asia. The Group has also built up a solid track record in North America and holds around 30% share in 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. 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.

TOPICS - Helping to Address Social Issues

Improved Fuel Efficiency: Making Cars Lighter with Multi-Material Components

Around the world, as environmental regulations become ever more stringent and customer needs grow more sophisticated along with the trend toward safety and greater comfort, the traditional solution proposal method focusing on a single material is becoming obsolete. Today, proposals involving multiple materials and a range of products are becoming the norm. Leveraging our current product lineup and technical capabilities, we must switch to offering multimaterial solutions, where different types of materials are combined to create optimal materials.
The Group is implementing a new business model that realizes customer value by making use of its range of multi-materials, including glass fiber reinforcements and metal resin composites, and by providing solutions combining materials and fabrication technologies at the Mobility Development Center established in April 2017.

Improved Safety: Improving Driving Technology with ICT

With the rise of next-generation automobiles featuring autonomous driving support technology to meet new needs for improved safety, customers are demanding performance improvements in view and sensing cameras. Most automotive lenses are currently made of glass, but the switchover to plastic lenses is expected to gain momentum mainly because of the greater degree of design freedom offered by plastic as well as mass producibility and cost savings.
The Group is moving quickly to develop automotive applications for APEL™, which boasts a high adoption track record for use as convex imaging lenses for mobile cameras, such as those installed in smartphones. The product is a transparent optical resin (cyclo olefin copolymer) featuring high refraction and low birefringence, but lenses for automotive applications require long-term reliability. We will enhance APEL™ for use as a plastic automotive lens, ensuring top performance in the area of environmental resistance, such as to heat and humidity. This will help improve the performance of sensors and improve autonomous driving support technology.
