Raiglon Apache Fluorocarbon Флуорокарбон
Extremely strong well-balanced 100% fluorocarbon.
In terms of strength, it is slightly inferior to nylon, but it has excellent scratches, scratches, and abrasion resistance, and is particularly excellent in durability. Since it has no water absorption (0%), it does not deteriorate in water. It sinks quickly with a specific gravity of 1.78. (Nylon 1.14 / Ester 1.38), Refractive index 1.42, close to water 1.33 (Nylon 1.53 / Ester 1.60), so the line is hard to see in water, and it can be connected and stored compactly by using an ultra-thin connecting spool.
