Recent years have seen a massive growth in the use of round slings (Heavy Lift) made with Dyneema® to replace steel wire ropes. Discover better ways to assess the in-use condition and residual life expectancy of synthetic EXTREEMA® round slings made with UHMWPE fiber.
Dyneema® is a super-strong fiber made from Ultra-High Molecular Weight Polyethylene (UHMwPE). The secret to the superior performance of Dyneema® fiber (UHMwPE) lies in the extremely long molecular chains that transfer load more effectively to the polymer backbone. As a result Dyneema® offers maximum strength combined with minimum weight. It is up to 15 times stronger than quality steel and up to 40% stronger than aramid fibers, both on weight for weight basis. Dyneema® fiber floats on water and is extremely durable and resistant to moisture, UV light and chemicals. The applications are therefore more or less unlimited.
