High-modulus-polyethylene is an extruded or gel-spun fiber that can subsequently be used in forming various items. If you braid it, it becomes braided line. If you don't braid it, it's not braided anything.
The similarities to nylon are obvious. Nylon can be extruded as monofilament line, of the very fine spinnerets can be braided into braided nylon line. I used to use braided nylon line, but the market isn't there anymore.
Like nylon, HMPE can be combined with other materials to achieve a desired effect. HMPE can be combined with carbon ("graphite") to create lighter and stronger replacement hip joints.
That's not braid. That's not even linear extrusion.
You'll notice that the ad has a trademark symbol next to Hyper Copolymer. That doesn't mean that Hyper Copolymer necessarily means anything, it simply is an advertising name they use. They could have used the term "Lightning Aggregate" or "Polyglot Extrusion Fibers", and then trademarked that. It makes no difference. Trademarks are IME signs of high-level BS.
Not only that, but there is no comment about content percentage of HMPE. They could include .000001% and still advertise that they had included HMPE in the line. I don't know whether they did that, but the ad copy is very "loose", if you know what I mean.
Until we obtain more accurate information, the most accurate statement that can be made is that Sufix Advance Monofilament contains, among other things, the same plastic that is used to make Dyneema and Spectra braided fishing line. How much and in which form, we don't know.
Enjoy the line. I have used 12 lb. test, and I still use 4 lb. test on an ultralight. All advertising aside, I think it's okay line. jj
