[Strong Cord] The kevlar kite line has amazing tensile strength even in the face of strong winds. It holds your kite firmly like a wire without worrying about breaking. [Sturdy and durable] The 100% Kevlar cord has excellent abrasion resistance, and the strong braiding and twisting process increases the durability of the line and greatly reduces the frequency with which you have to change your cord. [Low Stretch] Give your kite a professional accessory upgrade! The low stretch of Kevlar kite string allows any change in kite movement to be quickly reflected in your hands, and also means that any subtle movement you make can be easily transmitted to the kite, making it even more fun to fly. [Lightweight Line] Thin and lightweight Kevlar kite string can greatly reduce the weight of the kite. Replacing the traditional kite string, the ultra-light Kevlar kite string allows the kite not to miss every gust of wind and can fly high in the air easily and quickly. [kevlar Rope for Outdoor] Kevlar is abrasion resistant, stretch resistant, flame retardant and lightweight, shows its talents in various outdoor activities. Such as fishing line, emergency rescue rope, model rocket recovery harnesses/shock cord, hammock ridgeline, arborist throw line, trap snaring rope, restring wind chimes, RC crawlers tow cables/winch lines, tent rope, etc. 9KM DWLIFE Braided Kevlar Line Material: 100% Kevlar Fiber Color: Nature Yellow Diameter of Braided Line 750lb(dia.): 2.0mm 1000lb(dia.): 2.3mm 1500lb(dia.): 3.0mm 2000lb(dia.): 3.5mm There will be a certain error in the measurement (±2~3%) Notice:Data of the cords' marked strength comes from laboratory test.However, in practice there are a wide variety of factors.Therefore, the suggestion from us is for all kinds of cords, the safety strength is around 20% of its original strength. Braided Kevlar Line made of Kevlar fiber is a more durable rope. Because of its excellent abrasion resistance, Kevlar fiber is more used in outdoor field activities. The weaving process upgrades the toughness of the rope, even if it is used for a long time, there is no need to worry. Super Cut-Resistance. Kevlar string won't disappoint you when other kite line (non-Kevlar) crosses/touches it in flight.Kevlar has excellent cutting resistance and toughness, and it can even cut wood with Kevlar wire and it does it excellently. Lightweight, but strong cord. Its small and takes up hardly any space, very highly portable. Ideal choice for outdoor carry. High Flame Resistance. Kevlar line is one of the most heat resistant line. Kevlar begins turn to ash at about 800 °F. The decomposition temperature much higher than nylon or polyester. Kevlar Line is great for many outdoor activities, such as kites flying, fishing, rocketry, camping, hiking equipment fastening, backpacking tarp line, decoration etc. Perfect for situations where ultimate tensile strength performance is required.
