    amsteel vs dyeema

    I'm still reading, studying, designing, and planning. I've bought a budget hammock to begin my research and experimentation, but I continue to run up against new things like the difference between Amsteel & Dyeema.

    Can someone here please lay out the difference between these two lines?

    Amsteel is a product name for cordage made with dyneema fibers, so Amsteel is dyneema. It can be quite confusing!

    Dyneema is a product name for cordage made with high molecular weight polyethylene fibers. So is Amsteel. It can be quite confusing! The coatings on the manufactured ropes may be slightly different, but they are essentially the same stuff.

    Amsteel is a brand name for Samson cord made of high-modulus polyethylene (HMPE)--also known as Ultra-high-molecular-weight polyethylene (UHMWPE)

    Dyneema is the trade name for UHMWPE made by the DSM company in the Netherlands.

    Spectra is the trade name of UHMWPE made by Allied Signal/Honeywell International Inc in the USA. Dyneema was initially licensed to Allied Signal by DSM to be manufactured in the USA and the name was changed.

    Samson, New England Ropes, Yale Cordage, and other rope companies use Dyneema or Spectra fiber and then make their ropes with their own brand name (such as Amsteel, Dynaglide, Endura-12, Maxibraid, Ultrex, etc) Many of them are available in different diameters depending on the required specs. Some minor differences in coatings.

    No, you were entirely correct. Samson uses Dyneema SK-75 fiber to make their Amsteel.

    Most commonly used cords here on HF:

    Amsteel Blue: Made by Samson of Dyneema SK-75. 12 strand and spliceable. Available in multiple colors and diameters.

    Dynaglide: Made by New England Ropes using Dyneema SK-75. Also 12 strand and spliceable. Only available in bright orange and green with slick/waxy coating. Only available in 2mm diameter. STS-12-75 (also made by NE Ropes) is a similar 2mm cord to Dynaglide but with a different coating more like Amsteel.

    Lash-it/Zing-it: Made by Samson of Dyneema. I believe only 8 strand (might be wrong here). Spliceable. Only two diameters each (1.8 and 2.2mm). Lash-it is gray. Zing-it is yellow. Neither has a strength rating with a high enough safety rating for hammock hanging, but both are good for tarp lines and such.


    Each of these cords are sold by multiple vendors.
