Wilmington, Del.-based DuPont has merged its Advanced Fiber Systems, Nonwovens and Personal
Protection businesses into DuPont Protection Technologies, based in Richmond, Va. Products and
technologies offered include Tyvek® and Sontara® nonwovens, Kevlar® and Nomex® advanced fibers, and
Tychem® protective apparel, among other offerings.

“We believe we will be able to quickly simplify internal processes, increase the speed of
decision-making, and more fully leverage our large investments in research and development across
market segments,” said Thomas G. Powell, vice president and general manager of the new business,
who formerly led Advanced Fiber Systems. “These changes will lead to more rapid innovation and
improve our responsiveness to customers.”Production and research facilities of the three businesses
will continue to operate as before. “These businesses … represent applications and technologies
that DuPont is counting on for future growth. We are committed to continuing to invest in capacity
and innovation to meet the current and future needs of our customers,” Powell said.
