1957 First European Plant

The origins of the Maydown project grew out of a dispute with the British chemical giant ICI. In the early 1950s, ICI opened a U.S. dye facility. In response, DuPont’s Organic Chemical Department laid plans to enter the British rubber market by building a neoprene plant. In 1957, DuPont UK Ltd. announced plans to build that plant on a former naval airfield at Maydown, seven miles from Londonderry, Northern Ireland. Construction started that year. Since it began operations, Maydown also has manufactured Orlon, (from 1968) Lycra (from 1969) and Hypalon. These products have subsequently ceased production or, in the case of Lycra, transferred ownership.



Maydown started producing DuPont™ Kevlar® in 1988 and as of 2012 was one of only four Kevlar plants in the world, and the only one in Europe. Maydown helps supply Kevlar globally but also continues to develop new and innovative products.
