Choosing A Fluorocarbon Line – 4 Things To Consider


Many manufacturers of fishing lines are engaged in the production of fluorocarbons. This type of fishing line has found application in spinning, float and feeder fishing. Nowadays, not only professional anglers can use fluorocarbon line but also it is available to everyone. Thanks to the properties and quality of this material, fishermen can achieve better results.

So what should you pay attention to when buying a fluorocarbon line?

Let’s consider 4 main things that you need to know about the fluorocarbon line.

What is fluorocarbon?

The chemical compound fluorocarbon was originally developed and patented in 1969 in by Kureha Chemical Industries Co. It was used in the chemical and petrochemical industries. In the seventies, the first fluorocarbon lines appeared on the markets of North America (Seaguar) and Western Europe (Riverge).

Fluorocarbon monofilament or “polyvinylidene fluoride” (abbreviated as PVDF) is successfully used as the main line in ultralight fishing in those places where there is a high pressure from the fishermen and the fish are very careful. In addition, fluorocarbon is perfect for making leaders.

Advantages of fluorocarbon lines

Advantages of fluorocarbon lines

  • The refractive index of this material is close to that of water. If compared to nylon with the refractive index of light 1.6, fluorocarbon has the index 1.42. So the fluorocarbon line doesn’t reflect in the water. As a result, it becomes invisible to fish. This is especially valuable property when using the line for leaders. It greatly improves the results of fishing.
  • The strength of conventional lines is reduced by 5-10% due to the fact that they get wet and absorb water (about 10% in 24 hours). With fluorocarbon, this will not happen, even if the line is in the water for several days. So it doesn’t lose its strength. It is also not subject to destruction under the influence of frost.
  • Another advantage of the fluorocarbon line is its rather high density – 1.78 g/cm3. The density of nylon line is 1.14 g/cm3. So, PVDF is heavier than traditional materials of fishing lines. It is also heavier than water by 78%. Due to this indicator, a fluorocarbon line will almost instantly sink. This is undoubtedly a benefit, especially when fishing with a float rod and for fly-fishing.
  • The fluorocarbon lines are highly resistant to abrasion. Therefore, they are ideal for catching fish in ponds with shell or rock bottom.
  • Fluorocarbon is quite resistant to aggressive chemical agents, temperature drop, humidity, mechanical effects, as well as to ultraviolet. For comparison, nylon line suffices 50 hours of intensive ultraviolet irradiation. PVDF withstands more than 1000 hours of irradiation. Fluorocarbon lines are able to withstand and not lose their positive properties in the temperature range from -40 to +160°C.
  • Many fishermen note the rather positive property of the fluorocarbon line is the lack of memory to the bends. Even after tying the knots it remains flat and has no bends.

Disadvantages of fluorocarbon lines

Disdvantages of fluorocarbon lines

A fluorocarbon line has a number of advantages but it also has some negative properties. Here are these disadvantages:

  • One of the most unpleasant moments of a fluorocarbon line is breakage of tackle at jerks or a sharp increase in loading.
  • A significant disadvantage for many anglers is a higher cost of fluorocarbon line compared to other types of fishing lines. A high-quality fluorocarbon line has a big price. Not every fisherman can afford it.
  • Low strength of knots. This forces fishermen to purchase a line of larger diameter and study how to make special knots for fluorocarbon lines.
  • In addition, the rigidity of the material does not always have a positive effect on its application in spinning. Fluorocarbon is not always suitable for ultralight fishing. Fishermen sometimes make their choice in favor of a soft elastic monofilament line.

How to determine the quality of a fluorocarbon line?

Despite the fact that the production of fluorocarbons has fallen in price, the products from it still remain expensive. This especially concerns the lines produced in Japan where the cost of production depends on the expensive labor and the highest requirements for quality. Therefore, for real fluorocarbon lines, which are labeled as 100% Fluorocarbon or 100% PVDF, remain quite expensive.

As a budget option, you can find a nylon line covered with a fluorocarbon shell, which makes the tackle less noticeable. However, it will erase over time. Such fishing lines have a label “Fluorocarbon coated”. So when buying it is important to pay attention to this fact and not to confuse a 100% PVDF line with the coated shell.

Some manufacturers try to simplify the production process and mix nylon and fluorocarbon. As a result, such fishing line is cheaper but it is also of lower quality. Though it gets the advantages of both substances, it also has their drawbacks. Such fishing line is hard to fit it well on the spool and it does not straighten out when unwinding.

In order to distinguish the fluorocarbon line from the mixed one, it is necessary to burn it. Remember that a kind of crumbling sooty lump forms on the high-quality line. On burning the nylon product, you will get solid and translucent pellets.

To determine the quality of the fishing line, you can also immerse it in water. If a fluorocarbon tackle is noticeable in the same way as nylon one, it means that this is a line of inadequate quality.

In any case, you should buy a line of well-known brands that are worldwide popular and have been on the market for many years.


Fluorocarbon occupies an important place along with a braid and a monofilament. This fishing line is useful in many situations and it gives fishermen certain advantages. To choose a quality fluorocarbon line, you should first look at their rating, which you can easily find on the Internet.
