Expansion of Heat Release Material Business in the United States

Established a new plant in the U.S. to produce thermal gap filler materials for EVs and other environmental friendly vehicles.

  SEKISUI CHEMICAL CO., LTD. (President and Representative Director: Keita Kato; hereinafter "SEKISUI CHEMICAL") has decided to establish a new plant in the United States to produce thermal gap filler materials for EVs (electric vehicles) and other environmental friendly vehicles of its consolidated subsidiary, SEKISUI POLYMATECH CO., LTD. Construction of the plant is scheduled to begin in January 2023, and the plant will start operation in August 2023.

1. Background

  As part of global environmental initiatives, the shift from gasoline (diesel) to electric vehicles is accelerating in many countries and regions. In the U.S., in particular, the federal government is strongly promoting the spread of electric vehicles, and the production of electric vehicles in the U.S. market in 2025 is expected to reach 3.6 million, about three times the number produced in 2022. In line with this, the demand for LiB (lithium-ion battery) thermal gap filler materials is rapidly expanding among OEMs (automobile manufacturers) and LiB/electrical component manufacturers in the U.S.
  Under such circumstances, our thermal gap filler materials have already been highly evaluated by vehicle manufacturers and LiB manufacturers in Japan, China, and Europe for their excellent performance, including low outgassing, in addition to high thermal conduction performance. Against this backdrop, SEKISUI POLYMATECH have decided to build a new production base in the U.S. in addition to our current four production bases in Japan, Thailand, China, and Europe.
  In addition, the High Performance Plastics Company of SEKISUI CHEMICAL positions the mobility field as a strategic field. We will strengthen and accelerate marketing activities in the U.S. and Europe to further expand our heat release material business, and focus on the development of new products for mobility.
