DuPont Develops New Kevlar® Variant

Wilmington, Del.-based DuPont has developed a 300-denier variant of its Kevlar® fiber for use in
vests worn by corrections officers. Kevlar Correctional™ fiber technology provides excellent
puncture resistance, according to the company, and prevents sharp instruments from passing through
the body armor by dissipating energy and restricting the instrument from pulling the Kevlar
Correctional fibers apart.

The new fiber, which helps vests meet National Institute of Justice standard 0115.00, can
also provide threat protection from bullets and hand-made weapons when blended with other Kevlar
ballistic materials. Vests made with Kevlar Correctional technology also are flexible and
lightweight, enabling them to be comfortably concealed under uniforms.
