People who buy bullet proof vests for sale wonders what materials are being used to make these bullet proof vests. Actually, some manufacturers have been involved in developing and refining materials used in bullet proof vests.DuPont has developed law enforcement protection products for more than 25 years. Its Kevlar brand fiber, first developed in 1965, was the first material identified for use in the modern generation of a concealable bullet proof vest. Kevlar is a manmade organic fiber, with a combination of properties allowing for high strength with low weight, high chemical resistance, and high cut resistance. Kevlar is also flame resistant; does not melt, soften, or flow; and the fiber is unaffected by immersion in water.
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.
AlliedSignal also uses the Shield Technology process to manufacture another type of shield composite called Gold Shield. Gold Shield is manufactured using aramid fibers in place of the Spectra fiber. Gold Shield is currently made in three types: Gold Shield LCR and GoldFlex, which are used in a concealable bullet proof vest and Gold Shield PCR, which is used in the manufacture of hard armor, such as plates and helmets.
Another manufacturer, Akzo Nobel, has developed various forms of its aramid fiber TWARON for bullet proof vests. According to Akzo Nobel, this fiber uses 1,000 or more finely spun single filaments that act as an energy sponge, absorbing a bullet's impact and quickly dissipating its energy through engaged and adjacent fibers. Because more filaments are used, the impact is dispersed more quickly. Akzo claims their patented Microfilament technology allows maximum energy absorption at minimum weights while enhancing comfort and flexibility.
Law enforcement body armor and tactical vests are both made up of the materials mentioned above.
