Dyneema rope has one of the highest strength to weight ratios of the performance fiber ropes available, and can be up to 10X lighter than an equivalent strength steel cable. Dyneema fiber is made from a High Modulus Polyethylene (HMPE) that carries exceptional properties in relation to high strength, low stretch, low weight, and low friction. HMPE fiber is also considered the lightest of the high modulus fibers, and will float in water. Dyneema rope provides excellent strength with minimal weight.
