AmSteel is a 12-strand construction of Samthane-coated Dyneema SK-60 fibers and is an economical alternative to AmSteel-Blue.
AmSteel is a non-rotational rope that yields high strength and low stretch equivalent to wire rope, but with only 15% the weight!
This rope has a very high strength-to-weight ratio, is stronger than wire rope constructions, yet it floats.
In addition, it's flexible, easily spliced, and resists flex-fatigue and abrasion.

The Samthane coating is abrasion resistant, and has different formulations for specific rope fiber types.
The Samthane coating adds firmness and greatly improves wear life.
It also enhances abrasion resistance, reduces cutting and snagging, and helps prevent contamination.

AmSteel's combination of light weight, high strength and extremely low stretch has applications in competition grade running rigging, kite/wakeboard/waterski lines, trawl and bridle lines, and as low stretch support lines (wire replacement).
It is ideal for dinghy lifting bridles.

Elongation when loaded at 30% of breaking strength is less than 1%
Constructed with Dyneema SK-60 HMPE (high molecular weight polyethylene) fiber
Does not absorb water
12-Strand hollow braid construction
Splicing technique: full-bury 12-strand splice
Strengths in specification table are for spliced lines

Heavy on the technical side...

Dynema is the Dutch company DSM Dyneema's brand of UHMWPE (Ultra High Molecular Weight PolyEthylene fiber), a long chain, high strength, oriented strand, synthetic fiber with very high strength as well as high abrasion resistance.
This fiber is also known as HMPE (High Modulus PolyEthylene).
Dyneema is available in a number of formulations, SK-60, SK-75, SK-78, SK-90, etc. Each progressively stronger and more expensive.

Honeywell International produces a similar UHMWPE fiber, marketed as Spectra
