What Is Stren Fishing Line Made Of?

Stren fishing line is one of the most popular brands of monofilament fishing line on the market. It is known for its strength and durability and is used by many serious anglers around the world. But what is Stren fishing line made of?

Stren fishing line is made from a special polymer called polyvinylidene fluoride (PVDF).

PVDF is a thermoplastic fluoropolymer that has excellent strength and abrasion resistance, as well as chemical and temperature resistance. It also has low water absorption and excellent UV resistance, making it ideal for use in outdoor environments. This makes it perfect for use in saltwater or freshwater, and in any climate or weather conditions.

The PVDF used in Stren fishing line is stretched to give it added strength. The stretching also helps to reduce memory, which can cause the line to twist up when being reeled in. This stretching process makes the line more flexible and easier to handle, yet still provides enough strength for successful catches.

Stren fishing line is also treated with a special coating that helps protect it against abrasion, UV rays, and other environmental factors. This coating also helps reduce friction between the line and the rod guides, making it more comfortable to use.


In conclusion, Stren fishing lines are made of a specially formulated polymer called polyvinylidene fluoride (PVDF). This material has excellent strength and abrasion resistance properties which make it very suitable for use in both freshwater and saltwater environments.

The PVDF is stretched during production to give added strength while reducing memory issues which can cause twisting when reeling in. Finally, Stren lines are also treated with a special coating to further protect them from elements like UV rays or abrasive surfaces.
