DuPont Electronics & Imaging completes new plant in Cheonan in Korea to produce liquid polyimide for flexible display substrates

  • New plant designed to meet fast-growing demand for liquid PI for flexible display substrates
  • DuPont has made significant investments in Korea for the last two decades in research, production and localization efforts

SEOUL, Korea, Sept. 18, 2019 – DuPont Electronics & Imaging today announced it has completed a new plant dedicated to liquid polyimide (PI) for flexible display substrates to respond to fast-growing customer business needs in the flexible display market.

The new plant inside DuPont’s Cheonan Site located in the Cheonan Foreign Investment Zone in Chungnam Province in Korea will roll out colored and colorless liquid PI, a cutting-edge material essential in manufacturing foldable, rollable, bendable or transparent displays. Liquid PI can replace hard and brittle glass substrates, supporting various form factors for displays, and colorless PI is an essential part of the transparent display substrate.

Over the past two decades, DuPont has made significant investments in Korea’s electronic material industry. In Cheonan plant, the company is producing high-tech materials to serve customers in the semiconductor and display markets. It is also developing new electronic material technologies at its R&D center in Hwaseong, Gyeonggi Province in Korea. The new liquid PI plant is the latest addition to the company’s ongoing localization efforts spanning production and research facilities across Korea.

“DuPont pioneered the development of polyimide in the industry and has been a leader in the market for many years. The Cheonan plant based on this technological prowess represents our production hub in East Asia where major display manufacturers are clustered and it is paving the way for our leadership in the flexible display market whose growth is expected to escalate rapidly,” said Sang-Ho Kang, Display Technologies Global Business Director in DuPont Electronics & Imaging.

In recognition of its continued investment in Korea, DuPont was recently given an excellent investor award from Chungnam Province.
