Alliedsignal Spectra® shield is one of the the strongest, lighest man made fibers. Spectra® pound-for-pound is 10 times stronger than steel, 40 percent stronger than aramids and stronger and lighter than virtually every other comercial high modulus panel. It floats, resists chemicals and water, and exhibits superior fiber-to-fiber abrasion. It has excellent vibration dampening, flex fatigue and internal fiber-friction characteristics.

Spectra® fiber's outstanding visco-elastic properties means that the faster and harder the impact from a bullet, the stronger these fibers become, making them ideal for hard and soft body armor.

Spectra® fibers are used in numerous applications, including police and military ballistic vests; helmets and armored vehicles; sailcloth; fishing lines; marine cordage and lifting slings; and cut resistant gloves and safety apparel
