Overview of Business

High Performance Plastics Company

Business Fields

We are developing our business on a global scale, focusing mainly on three strategic fields: Electronics, by which we are providing materials related to a variety of displays, electrical and communications equipment, substrates and semiconductors; Mobility, by which we provide materials related to automobiles, such as interlayer films for laminated glass, and components for aircraft; and Industrial, by which we provide products created from cutting-edge technologies, such as adhesives, packaging tapes, and plastic containers for use in daily life and throughout society.

Features/Business Strategies

We are developing a wide range of businesses with a focus on materials for the advanced fields in which our strengths lie, for example, our original fine particle, adhesion and precise molding technologies. Possessing multiple product lines with top global market shares (based on SEKISUI CHEMICAL estimates), such as conductive fine particles, liquid crystal sealants, interlayer films for automotive laminated glass, and polyolefin foam for automobile interiors, we are developing our business centered on high-value-added products.
While aiming to expand faster than the market growth rate, we are working to augment our operations by enhancing our existing core products, developing new products, and through M&A.

Urban Infrastructure & Environmental Products (UIEP) Company

Business Fields

Our core business is the manufacture and sale of polyvinyl chloride (PVC) piping materials, in which we boast the leading market share in Japan, and infrastructure-related materials. We are developing business on a global scale in three fields: the Pipe Systems field that provides pipes for the public and private sectors, high-performance piping materials for plants, and chlorinated polyvinyl chloride (CPVC) resin compound; the Building and Infrastructures Composite Materials field, such as the fiber-reinforced foam urethane (FFU) synthetic wood used in the railway sleepers; Infrastructure Renovation field, such as infrastructure rehabilitation.

Features/Business Strategies

Based on the technological capabilities cultivated in our core business, we define as Prioritized Products those from which high-value-added market growth is expected or products that we expect will enable us to substitute conventional materials (metal, wood and glass) with plastic products and that we will then aggressively introduce into the market. Including those products that contribute to corrosion resistance and ease of construction, natural disaster countermeasures, and infrastructure reinforcement, Prioritized Products are contributing to the solving of social issues that are worsening and becoming more complex, such as the shortage of construction workers (avoidance of the 3Cs: closed spaces, crowded places, and close-contact settings), the aging of infrastructure, and climate change.
Overseas, we are developing materials that include transportation infrastructure and pipeline renewal materials for Europe and the United States as well as pipe materials for Asia. At the same time, we are aiming to further expand and deepen our sales areas with a focus on high-value-added products.
