Kevlar 29, introduced in the early 1970s, was the first generation of bullet resistant fibers developed by DuPont and helped to make the production of a flexible, concealable bullet proof vest practical for the first time. In 1988, DuPont introduced the second generation of Kevlar fiber, known as Kevlar 129. According to DuPont, a bullet proof vest with this fabric offered increased ballistic protection capabilities against high energy rounds such as the 9mm FMJ. In 1995, Kevlar Correctional was introduced, which provides puncture resistant technology to both law enforcement and correctional officers against puncture type threats.
The newest addition to the Kevlar line is Kevlar Protera, which DuPont made available in 1996. DuPont contends that the Kevlar Protera is a high-performance fabric that allows lighter weight, more flexibility, and greater ballistic protection in a bullet proof vest design due to the molecular structure of the fiber. Its tensile strength and energy-absorbing capabilities have been increased by the development of a new spinning process.
Spectra Shield® products have been protecting military and law enforcement personnel for the past 20 years, and that history of innovation continues with the release of the Spectra Shield® II product line.
SR-3124, a Spectra Shield® II hard armor product, incorporates high-strength Spectra® 3000 fiber into hard armor shield construction, to provide the highest levels of protection for breast plate, helmet, and vehicle applications.
SA-3118 and SA-3113 are the Spectra Shield® II soft armor offerings, providing the best known ballistic protection for military and law enforcement vest applications. SA-3118 maximizes ballistic performance, while SA-3113 was designed for added flexibility and comfort, while maintaining a high level of performance.
SR-1214 is the standard Spectra Shield® hard armor product, used in plate, helmet and vehicle programs throughout the world.
SA-1211, continues to be used in some of the most demanding vest applications, and is designed to meet the comfort and flexibility demands of the user, while maintaining strong ballistic performance and reducing the effects of blunt trauma.
