This cord is made out of SPECTRA that is even stronger then KEVLAR. Its main disadvantage is it has a low melting point. I use it for climging and it is great for making slings etc... One of the hard thing to deal with is cutting it. I usually have the climbing shop cut it with an electric heat knife. It will work if you want to haul some thing or as a lifeline etc... but 550 cord is better for all purpose. You can also get it in I think a 3 or 2 mm for tent guidelines.
