RESEARCH TRIANGLE PARK, NC — DuPont Circuit & Packaging Materials has begun a major expansion of its production capacity at its Circleville, OH, facility, where it makes Kapton polyimide films.

The expansion will add up to 400 tons of available capacity as well as new manufacturing capabilities, the company said.

The new production is expected to come online in the fourth quarter.

“This expansion supports our commitment to reliable supply and leading-edge innovation for our customers and the industry,” said Peter Irvine, global business director, DuPont Circuit & Packaging Materials.  “Demand has been strong and will continue to grow.”

As part of the expansion, DuPont is extending its manufacturing capability to meet aesthetic design requirements, including color and clarity, as well as enhance performance properties such as thermal conductivity and corona resistance.
