DuPont wins 20-year ban in Kevlar row with Kolon

NEW YORK, -- U.S. chemicals giant DuPont has won a 20-year global ban on a Kevlar rival product made by South Korea-based Kolon industries after a court found Kolon had stolen its trade secrets.
“The trial court ordered Kolon to not produce, market or sell any para-aramid fiber products, worldwide, for 20 years,” Thomas Sager, DuPont's general counsel, said in a statement Friday.
“It also permanently enjoined Kolon from using any of the trade secrets it stole from DuPont,” he added.
The ruling, issued late Thursday by a U.S. federal court in Richmond, Virginia, followed Kolon's trial loss in September 2011 when a jury found it had stolen DuPont's trade secrets on the manufacture of Kevlar aramid fiber.
Kolon, which produces and sells Heracron aramid fiber, has been ordered to pay more than US$920 million in damages and interest.
Sagar said that the federal court gave Kolon until Oct. 1 to remove and return DuPont's trade secrets or face contempt proceedings.
Kevlar, an antiballistic fiber used in military and police gear, also is used in a number of products, including tires, fiber optic cables and spacesuits.
