NER V12 vectran single braid

I was looking at the marine section of the New England Rope website and noticed that they have a vectran 12 strand single braid. My question is: Can this be used in the same way as samson,s ice tail? Also what exactly is the difference between vectran and technora?
Thanks, Ted
 
Icetail is technora with polypropylene in the center of each of the 12 strands to cut down on cost and weight.

To put it in a nutshell; (1)technora will tolerate tight radius bends more than vectran; (2) technora is a derivative of kevlar, 900* charring point; (3) vectran has it's own molecular structure and a charring point of 625*, compared to 480* melting for polyester. Both will not hold a flame. Icetail was designed for friction hitch applications.

I have used both for friction hitch applications and find that technora lasts longer. Vectran is also more $.
 
NE Ropes makes HRC, a 12 strand vectran hollow braid with a Nomex/Technora cover... I think they call it Therma-Shield Prusik.

It's great stuff, you splice it like any 12 strand hollow braid and just whiplock the cover over it leaving the eye exposed... you dip the eye to keep it from picking.

For my taste it's the most sensitive yet controllable split-tail cord I've ever used... by a wide margin. It doesn't glaze at all. It does take a distinct set in terms of twist but it doesn't affect the performance at all.

I did have some trouble with it gripping wet Velocity the other day. It was just with the initial grip, once it was under load it held on fine. It grips Poison Ivy wet or dry no problem. Haven't used it with any 16 strand ropes.
 
Banjo- I've had good success with the vectran 12 strands, but this was before beeline, HRC, icetail, etc. The V12 is woven VERY loosely and it snags easy.

There are much better things to use these days. Spend money on those, instead.

FWIW, the vectran seemed to be VERY resilient and could handle tons of abuse.

Thanks everyone. I'll just stick with ice tail for now. My idea was that a finished eye to eye split tail spliced like tenex or ice tail could have a smaller finished diameter. Are there any ropes out there more like ice tail that come in smaller diameters?
Thanks Ted
 
Hi Banjo,

Here are a couple of pictures of a product that is similar to Ice Tail, but a smaller diameter.

The greenish blue rope is the Ice tail, you probably recognize that, but the yellow one is some technora cord. Similar construction as the Ice tail as you can see, but smaller size. Both have the high heat resistance and splice the same.

I like the Technora. It is also tough as nails to cut.

Yep, we have certainly noticed that this rope fiber is difficult to cut. The normal tool we use to get a clean cut prior to splicing is one of those tough cut tools from Sears. Cutting any of these ropes, like Ice tail, tech cord, or our Kevlar prusik cord destroys the razor blade on that cutter almost immediately.

Whenever we cut this rope now, we use a good pair of industrial scissors and they work real well.
 
Oh, and I want to echo Blinky's post about the HRC.

I love climbing on it, and the fact that I can't glaze it. I actually have been climbing on 16 strand with the HRC and it works fine. I have my eye on the new Tacheon rope from NE once that comes out this January.

Thanks John,
The smaller technora cord might just be what I'm looking for! Who makes it and what is it called? What is the finished diameter of the splice? I'm familiar with hrc/therma shield, I just like trying new things.

That smaller yellow technora cord is made by atlantic braids and sold in the US via all-gear.

John- is that the splice recommended by the manufacturer? Last time I checked, they didn't have directions for it. I have an older one that is spliced with locking brummels and long overlapping tails.

I have a ceramic knife that I use for cutting all high-mod lines (dyneema, technora, vectran, pbo, kevlar, etc.). It works like a charm, especially if you take 1 wrap of masking tape before you cut. I've never sharpened the thing yet...it just keeps going and going and going.

I've found the next best thing to be a razor utility knife. I would replace the blades once or twice a month. The ceramic knives are expen$ive...but worth it when you don't have to buy more razor blades!

Nick,

Regarding the splice in the yellow tech cord, yes, that splice is actually the "factory designed splice". I personally have a few of them spliced like that and have been climbing with them for a couple of years. For me, those split tails are used in conjunction with a micro mouse and distel hitch. The interwoven part of the splice is flatter compared to a brummel and I like that on these split tails. On top of this, when the eye splices are made extra tight they don't slop around on the carabineer.

Needless to say, these have proved to be very stable and reliable. I have never had one go bad on me, that splice locks down real tight and I feel very comfortable using them. They are stitched for extra security.

In any case, the ones we send out the door are done with a brummel splice unless the customer specifically wants it spliced like the one in the picture.

That smaller tech cord is a sweet little number though, I like it a lot.

That ceramic knife idea sounds like a good one; I'll have to give that a shot.

Thanks for the tip.
 
Ted, you don't have to 'tuck' the Tech cord. I've been doing strate buries for over 2 years now. Just make sure the splice is stitched.
See attachment. The cord on the top is Tech cord 5/16" diameter, the bottom is Samson's Tech 12 in 3/8" diameter.

Norm, good point. Those crossovers may not be providing anything if they are not locked. The straight bury is much more elegant looking, too.

I know the straight bury is recommended by Samson for their splices. Yale recommends a couple passes (not locked). I'm a fan of locking brummells.

Can anyone tell me how long a length of Ice to use for a standard eye & eye? I am buying in bulk to make Christmas presents for some friends and am not sure how much to get. Thanks,

-Ryan
