Dyneema has a slightly different molecular structure than spectra and higher breaking strength in the larger diameters. It displays slightly better wear characteristics in heavy use areas, but has more elasticity than Honeywell's Spectra 1000. This fiber is popular in Europe and is gaining popularity in the states. Examples of cordage containing Dyneema: Amsteel Blue, Warpspeed, Superbraid, Ultrex, LOUPS.
