High Abrasion-Resistance
One of the best advantages of Kevlar line. It helps avoid many unexpected string snaps which happen a lot in binding, fastening objects or uses near sharp edges. In addition to "resistance" properties, Kevlar line is also highly resistant to abrasion, to chemicals (especially acids, and alkalis.)
Flame Resistant-Capable to Work at High Temperature
Kevlar doesn't melt and only decomposes at relatively high temperature, which makes it the common and popular material in firefighter PPE equipment.
Toughness - Yields High Strength in Small Size
High tensile strength cordages in lightweight, 10X greater than steel on an equal weight basis. A roll of 100ft 550lb kevlar weighs less than 3 Oz, light and compact to carry on person in the wild.
Low Stretch, Least Creep
Stretch annoys much in applications like stringing hammocks, kite flying control, especially in control of stunt kite or traction kite. Kevlar cords have extremely low stretch and don't create creep even after long time loading.
SPECIFICATION
Material: 100% Natural Kevlar Yarn
Construction: Braid. The multi-strands interweaving process makes the Kevlar cord much more durable and able to resist raveling.
Decomposition Temperature: 800~900 °F / 427~482 °C. Kevlar doesn't melt like nylon or polyester. It decomposes at high temperatures.
Approximately ±2~3% deviation exists in measurement.
Safe Working Load Limit: 20% of the tensile strength, for the longevity of the cord and safe uses
Packaging: On roll
Tensile Strength & Working Load Limit
Working Load Limit (WLL) = 20% of Tensile Strength, for the longevity of the cord and safe uses
Tensile Strength
Also known as the labeled strength, is the average strength at which the new and unused cord would break when tested in laboratory condition in accordance with Cordage Institute Standard Test Methods. The load, applied in parallel to the cord, slowly increases until the cord breaks.
Working Load Limit (WLL)
In the real world of practical uses, there are various factors that would impact or reduce the strength of any rope/cord, including knots in the rope, abrasion, humidity, UV, former use and care, etc. To assure safe uses, it's indispensable to adopt a safety margin in the cord/rope strength, which leads to Working Load Limit (WLL).
The Working Load Limit (WLL) is determined by dividing the tensile strength by a safety factor. To assure the longevity of the cord and maintain a comfortable margin for safe uses, a 5:1 safety factor (20% of the tensile strength) is adopted and recommended for emma kites Kevlar cord for general applications.

Like many products I purchase - I use them for strange applications. This line, I used to create 4 small loops that attach to the lower housing of our 100lb outboard motor. I then clip into these looks with a harness I made to lift the motor from the dinghy onto our sailboat, for storage. The loops have bene holding up very well indeed.

When launching model rockets, the shock cord attaches the rocket to the parachute. When the model rocket engine completes it burn, it blows the parachute and nosecone off the ricket, but sometimes the heat will melt the old shock cords. That is where this product shines. I replaced the old shock cord with this small light heat resistant cord. It works very well for this purpose. So - Model Rocket approved.

I recently used Kevlar Cord for a project and finished the ends with Adhesive lined Heat Shrink Tube. For the 1.7 mm Kevlar Cord, I opted for a 3/32" or 2.4mm Tube. The cord offered a more grippy texture compared to nylon fiber, and I noticed no stretching, making it ideal for applications like grip wrapping.The adhesive from the Heat Shrink Tube melts into the fiber, providing a secure connection and a polished appearance.

Strong but thinner than I thought.. works well and holds a ton of weight!

Using this for shock cords in model rockets. Been looking for this exact product. Lots cheaper than buying by the foot from rocket supply sites.

I dont know the metric sizes and bought this without checking. It's still good. You can braid it and it's useful. Replace guy lines on tents, use it to string laundry lines in the woods, etc. I've even used a length of it to hold a steel mug in fire to boil water.

I won't build a model rocket without this stuff these days. I have swapped out all the old elastic shock cords with kevlar and there are no more worries about burn-through or brittleness with age. The one roll I have bought has done many, many rockets (at about 3x the rocket length). No zips yet, but that is more a matter of proper staging than anything else. Tough as nails and worth its weight in gold. Love this stuff and will be buying more as soon as I need it. High quality for sure!

The line itself is fine. The spool is cheap. I purchased two of these and one of the spools was broken, and that was not from shipping. The package was fine. The broken spool makes the line difficult to use, as it easily tangles, even when transferring onto a new spool.

Great stuff!I got the 150lbs version. I plan to get more, and thicker too.- Thin yet super strong.- Can be tied pretty well.- Works amazingly well for some sewing tasks, especially when you need extreme strength without doing the stitch many times. Not for general clothing, etc, but I have found many uses for it for leather, quick denim repairs, etc. You'll want some thick needles to do this. Slightly thicker than come in most kits, but can easily be found in Amazon or a supermarket. I got some at Sainsburys and also a big pack at the 99p store.- Very cut resistant, although can still be cut with a knife or scissors, just takes a bit more force. Really excellent for the thickness though.- Seems like a fair price.Feel free to ask me questions in the comments.

Pas persuadé pour du kevlar Assist, j'ai impression qu'il tient pas du tout la chaleur...il brûle et passe en poussière en quelques secondes

corda molto resistente l'ho usata per sostituire la corda di acciaio che scorre su carrucole delle doghe del mio letto e finora nn ho notato nessun cedimento ne logorio

Sehr gute Eigenschaften am Lenkdrachen, auch mit einfachen Buchtknoten ohne Spleissen etc. sehr zugfest. Wenn die Schnur sich verdreht bleibt der Drachen gut lenkbar weil die Oberfläche schön glatt ist. Empfehlung.
