Here is a list of some of the most important characteristics of rope for most applications, and below the characteristics we show the corresponding characteristics of Dyneema/Spectra rope :
Low Creep – Creep is a measure of how much the rope stretches during load. The more the rope stretches, the weaker it gets.
Among high modulus Polyethylene fibers, Dyneema has the lowest creep and the longest creep life.
Temperature Integrity/Consistency – For uses in extreme climates and temperatures, it is vital to have a rope that has minimal changes in its strength properties.
Dyneema rope and Spectra rope (the same fiber) are very consistent in strength between the temperatures of -150° through 70° Celsius or
-238° to 158° Fahrenheit – a very robust temperature range that would accommodate most applications.
Tensile Strength- The most obvious characteristic of a good multipurpose rope is how well it holds up under a load.
Dyneema fiber is 15 times stronger than steel weight for weight, and can sustain the largest loads of any HMPF.
Here’s a great demonstration of how strong this fiber really is:
Weight – The ideal rope for many climbing, nautical/fishing, and many other applications is a rope that has high strength to weight ratio.
Weight for weight, Dyneema rope is 15 times stronger than steel. It has the highest strength to weight ratio of high modulus polyethylene fibers.
Water Resistance- Water resistance is important for a variety of reasons. First, fibers that do not absorb water will have more longevity. In addition, a fiber that does not absorb water will not become heavier when used in moist applications.
Dyneema rope absorbs no water.
Safety – A safe rope is the most important in heavy lifting or pulling applications. The user needs to be confident that should a failure occur, the break will not cause a trauma. Steel cable provides the best example of a “rope” that will cause trauma should an operator be in proximity to the cable during a failure.
Dyneema rope is completely safe during a break.
In addition to the above benefits, Dyneema rope is very resistant to acids, salt water, alkali, and chemicals. It also maintains its integrity through bending and impact.
What are some of the applications of Dyneema/Spectra Rope?
Dyneema 12 strand rope is used heavily in nautical/maritime, and fishing applications. In addition, it is a favorite of recreational climbers and arborists. For arborists, loggers and tree services, Dyneema’s resistance to oil and gas, and it’s cut resistance make it an ideal rope. Dyneema rope is also preferable to steel cable when lifting large log loads because of the increased lifting capacity and the reduced danger in the event of a break. For recreational rock climbers, the strength and resistance to cutting are most important.
