SEKISUI expands business in Europe
Construction of a new production plant for thermal interface materials for environmentally-friendly vehicles such as EVs in the Netherlands

Roermond, the Netherlands, August 2018. SEKISUI CHEMICAL CO., LTD. (President and Representative Director: Teiji Koge, hereinafter called “SEKISUI”) has decided to construct a new production plant of thermal interface materials for environmentally-friendly vehicles such as electric vehicles (EVs) for SEKISUI POLYMATECH CO., LTD. (CEO: Jun Yamazaki, hereinafter called “SEKISUI POLYMATECH”) in the Netherlands. The new company will oversee both the production of thermal interface materials at the plant and the sales expansion for thermal interface materials in Europe. There are plans to invest approximately 1.6 billion Yen (ca. 12.3 Mio. EUR) in establishing the new company, including the construction of the new plant.

The new company to be established in the Netherlands will be a wholly-owned subsidiary of SEKISUI POLYMATECH. The registration of the new company will be completed in August 2018, the construction will start in January 2019. The plant operations are planned to start in spring of 2020.


In Europe, many environmentally-friendly vehicles such as electric vehicles (EVs) and plug-in hybrid vehicles (PHVs) are being developed by original equipment manufacturers (OEMs). It is predicted that the number of such vehicles produced in FY2025 will increase to 12.5 million units, which is approximately 10 times the figure of 2017 1. With this trend, the demand for heat countermeasures for the lithium-ion batteries (LiBs) used to supply power to such vehicles is rapidly increasing.

SEKISUI's High Performance Plastics Company (President: Keita Kato) is expanding its business in the four strategic fields of electronics, automobiles and transportation, buildings and infrastructures, and life sciences. In August 2017, SEKISUI merged SEKISUI POLYMATECH (previous name: Polymatech Japan Co., Ltd.) together with Inabata & Co., Ltd. (President: Katsutaro Inabata) with the aim of enhancing its products in the automobiles and transportation and expanding its business in the electronics field. Since then, it has positioned its thermal interface materials, for which needs are increasing in the automobile industry, as a particularly important product, and is striving to quickly achieve synergy in this field.

SEKISUI POLYMATECH's thermal interface materials do not only offer high thermal conductivity, but also excellent abrasion resistance for dispensing equipment and low outgassing for the product itself. Therefore, they have been highly evaluated by OEMs and LiB manufacturers, and increased adoption accompanying expansion of the environmentally-friendly vehicle market is expected.

In light of these factors, the decision was made to enhance its production capacity by constructing a new plant in Europe, a major supply destination, in addition to its two current production bases in Japan and Thailand, and to establish a new company SEKISUI POLYMATECH EUROPE B.V. to perform all operations including production, sales, development and marketing.

2 SEKISUI has production plants for interlayer films for laminated glass, crosslinking polyolefin foam and rain gutters in Roermond City in the Netherlands. The new plant will be constructed on land owned adjacent to these existing plants.

3 SEKISUI POLYMATECH has a range of both sheet-type and grease-type (semi-liquid) of thermal interface materials. For the LiBs, particularly, there are strong needs for grease-type products that are suitable for production line automation, and there is a plan to produce grease-type products as a major product at the new plant for the time being.
