In the mid-1980s, Honeywell (formerly Allied Signal Inc.) introduced Spectra® fiber. An entirely new type of synthetic yarn, it was one of the first commercially available extended chain, high-modulus polyethylene fibers. Because Spectra® fiber is a polyethylene - with a carbon-to-carbon molecular structure like that of a diamond - it creates a continuous filament yarn with incredible performance and endurance. Pound-for-pound fifteen (15) times stronger than steel yet light enough to float, Spectra® fiber is one of the world's strongest and lightest manmade fibers. Spectra® fiber applications include cut protection, ropes and cordage, vehicular and personal armor, and fishing line, as well as various specialty applications.
