US-based DuPont Electronics & Imaging said Wednesday that it has completed a new plant in Cheonan, South Chungcheong Province, that will focus on the production of liquid polyimide (PI) for flexible display substrates.

The company is seeking to tap the growing demand for future materials that enable bendable displays.

Liquid Polyimide is a cutting-edge material that can replace hard, brittle glass substrates for various form factors such as foldable, rollable, bendable or transparent displays.

DuPont plans to roll out liquid PI from the plant. Colorless PI in particular is essential for transparent screens.

It has invested in South Korea for over two decades. The new plant, located in the Cheonan Foreign Investment Zone, represents the latest in its efforts to localize its production and research facilities here.

DuPont produces materials for semiconductors and displays at its original Cheonan plant, while it develops new electronic material technologies at the research and development center in Hwaseong, Gyeonggi Province.

The firm has been recognized as an excellent investor by the South Chungcheong provincial government since it was known as Dow Chemical, before its merger.
