Izorline, co polymers and mono

[ABurk]

Can someone explain the difference? I’m looking at this spool of izorline I have, and it has me scratching my head. It says it is the worlds finest copolymer monofilament line. The “co” and “mono” are throwing me off. I’m probably overthinking this as well, but I take things quite literally so when I read things like that and I can’t figure it out it drives me nuts. 

Added pic of spool for reference.

That's an odd statement, but I guess it works. Copoly and Mono are both nylon lines but copoly is more of a cocktail. You usually get less stretch and better abrasion resistance. It also tends to be a sinking line compared to mono which is a bouyant line.

 

Whether less stretch and decreased bouyancy is a benefit depends on your application.

I'm pretty sure it's copolymer.  Technically it is a monofilament, as the 'polyfilament' we use is braided line (usually 4 or more strands of Spectra or Dyneema polyethylene) .  Usually the monofilament nomenclature is used for a single kind of nylon (there are many molecular structures of these polyamides, after all) drawn into a single fiber.  So I would imagine there a couple of these kinds of nylons in this line made into a single fiber, making both terms technically applicable.

You’re way smarter than I am. I appreciate it lol

I doubt it, but at one time I made a.living as a chemist.

I’m still trying to make a living out of living. I appreciate your knowledge.

I may come to you with advice about living.  There's not much I get to use all those years in  school and a lab for these days, so it's good when I can put them to use.

BTW- It's a great line

I love the Super Copolymer XXX!!!?

Pretty much all i use besides big game for treble hook baits.

Mono is a term used in fishing for monofilament. 

To distinguish Nylon polymer from blended nylon/polyester etc, the line manufactures used copolymer for 2 polymers blended.

Izor line wasn’t the 1st copolymer fishing line. Maxima was available in the late 60’s before Russ Izor thought about private labeling line.

And in my humble opinion Sufix Advance Mono is the world's best COPOLYMER Monofiliament line made. Monofilament means one filament. In other words it's not a multistrand line. It can be regular MONO , COPOLYMER or flourocarbon. Yes guys flouro is a monofilament line. We just never call it that.

I'll have to test that - got a spool of 10# Advance I'll be putting on a couple reels.

Have you ever tried izorline?

 

[dodgeguy]

No but until Sufix Advance came along no mono had near as little stretch as Advance does. Being that I mostly used braid for 30 years with other lines mixed in including a bunch of mono and flouro it took until now to find one with so little stretch.

Mono and copoly are the same thing. Copolymer is a marketing hype term.

 

There are very few 100% nylon 66 lines available today, you would be hard-pressed to find one - the vast majority are a soup-mix of ingredients.

 

Fuoro is different though - it contains no nylon.

Semi true

 

Nylon mono lines are a mix of different nylon polymers - so yes, they're a 'co-poly' in that respect - but it's still all nylon, just different formulations.

 

Yo-Zuri Hybrid, Izorline Co-Poly, Sufix Advance and others are a mix of nylon and fluorocarbon. How they put them together differs based on manufacturer.

[dodgeguy]

As far as I know there is no flourocarbon in Advance. There is dyneema in it.

My oops - it's still two widely different materials though - so it does qualify as a 'true' co-polymer.

[ChrisD46]

I know lines such as Berkley Sensation and P-Line C-XX are co-poly lines - but what about Berkley Big Game and Sufix Siege , are they really mono lines ? (I like all of these lines by the way...)

[JustJames]

It is hard to tell which is mono or copolymer line. Tackle warehouse list them depends on what Manufacturer called it. Look at Trilene XL is under copolymer category while Trilene XT is mono.

To me it is hard to tell the difference, stretch, abrasion resistance or even memory of different brand mono/copolymer line (less than 10lb test) giving the line with same diameter. Once you go above 10-12lb or 0.012” in diameter then the softness of the line become more obvious, still some question mark on stretch and abrasion resistance.

Most of my line these days are Izorline 4, 6, 8 12 and 15lb because it widely available here locally and price can’t be beat.

[Gary_Snyder]

Those mono lines with Fluorocarbon in them don't "do" anything special....there is not enough fluoro in them to make a difference (That said, some of them are fine monos).

 

If you want something that's like fluoro, you have to go all the way with 100% fluoro
