Does Heat Help Or Hurt Line Memory?

[ghost]

What I mean is mono, copoly or fluoro line on a reel, when the rod and reel are inside a warm or hot car.

 

I am using P-Line CXX and just wondering if less memory on the line if inside a car.

 

Does line tend to get weaker when it's warmed up inside a car?

 

Also, does the warmth inside a car have affect on a reels oils and grease?

No expert on the subject, but...I would think that, and this depends on some variables, like how warm is the temps, for how long the line/oils are exposed at what temps, ect, ect. I think we all know that oils and some type of grease will lose viscosity when warm, and with age, i.e. like the oil in your car. 

 

Fishing line I'm going to say will become more pliable when warm, what that warm temp is, I guess depends on the line. But, if you think about it, in cold weather say around 50* fluro for example would likely retain more memory than if it was 80* to my way of thinking, of course, some fluro lines have more memory than others. Also, have to ask, how long does it take for a reel spooled up to absorb that heat, and how long does it retain it.?

 

If, I were using fluro, I'd rather use it warm weather, same for mono. Maybe someone here that has the knowledge on the subject can comment.

All plastics have a heat deflection and glass transition temperature rating.

In basic terms monofilament line made of neat resin meaning no fillers additives has a heat deflection temperate about 105 degrees F. Heat deflection. Is the temps the material starts to loose it's strength, glass transition is slightly higher about 110 degrees F where the material softens.

Copolymers have slightly higher temperature rating depending if blended with polyesters and fluorocarbon is a higher temperature plastic material. 

Basically mono and copolymers can be affected by temps inside a car during summer heat up not FC or braid.

Well, Tom kinda shot down my theory as far as fluro is concerned...

I soak all my spools in the hottest tap water I  can get for about 5 minutes. This removed all memory on the line permanently. I do not do this with braid just mono flouro and copoly/hybrid lines

That's interesting. I might try this.

My dad showed me that trick I must have only been 6 or 7 years old and I have never forgot it and I'll tell you it works. I just put them in a coffee cup with the hot water

Soaking in hot (130 degreeF) water should anneal Nylon, little affect on Fluorocarbon line unless the water is very hot 175 degrees F. Annealing can lower the tensile strength. What's is missing in this proceedure is time and it take hours, not minutes, for non thermally conductive materials to absorb surrounding temperature. Nylon is hygroscopic material, absorbs water and fluorocarbon is anti hygroscopic doesn't absorb water.

Will heat from a rod and reel sitting in my car for 8 hours, will it weaken the line? How about my fishing rod?

P-Line CXX is a large dia per llb test monofilament coploymer blended Nylon line.

I would't leave my rod/reels/line in a car when the outside temperature are 90 degrees, the inside could be over 130 degrees for a few hours od day.

I learned this a few years ago. Tried it once and have been doing it on my flouro & mono ever since. Can't say I've ever noticed any negative effects from it but it does make the line easer to manage.

Heat won't damage the line as as much the UV rays. The fishing rod itself will outlive all of us, but some of the thread wraps and handle materials don't do as well.

Don't know of any monofilament line that doesn't have some UV inhibitors as the line is made to be used sunlight, but wouldn't suggest storing line in direct sunlight. Exposure to extreme heat is your biggest issue storing tackle in a vehicle IMO. The rod blank should be OK, the adhesives used to build the rod is another issue.

A study done by Fish & Game found monofilament losing up to 20% of its strength after 100 hours of uv exposure. I'm sure some have better UV inhibitors than others, but none are impervious.

Agree UV and Ozone continuous exposure affects all plastics including Nylons. The best UV color is black pigments, fishing line is transparent and more susceptible to degradation. Fishing line is processed by extrusion, melted to pushed through dies, the cooled immediately in water trays, dried and wound on larger spools. The differences in quality is the processing.

We have always recommended storing line in a cool dark place to reduce degradation.

I like Nylon monofilament line but also recommend changing often, it degrades do to use. 

Fluorocarbon technically is far superior line regarding heat, UV, Ozone etc, if only it had equal knot strength. Braid isn't affected.

I wouldn’t use P Line Cxx on a small spool diameter bass reel. It is a great line, but for other applications.

High heat can absolutely damage fishing rods. The first gloomis I ever bought was ruined when some idiot (me) left it in a vehicle on a hot day pressed slightly into to ceiling creating a slight bend, well that rod has that same bend to this day ?‍♂️

Graphite prepregs are generally cured at 300° or more. It'd take a lot more than a hot car to damage the blank if it was properly cured at the factory. Fiberglass rods, especially older ones, are another story. Cheap epoxy can have issues as well.

Flip it 180° and let it sit in your car again ?
