Title:
PARALLEL UHMWPE ROPE
Document Type and Number:
WIPO Patent Application WO/2012/175610
Kind Code:
A3
Abstract:
The present invention pertains to a parallel rope comprising elongate bodies wherein the length axis of the elongate bodies is parallel to the length of the rope or wherein the elongate bodies show helix angles smaller than 2°, characterized in that the elongate bodies comprise tapes of ultra-high molecular weight polyethylene, the tapes having a width to thickness ratio of at least 10 and a polymer solvent content below 0.05 wt.%. It has been found that a parallel rope based on the specified polyethylene tapes shows high modulus in combination with low weight, a long life-span, and low creep. If so desired, the rope may be free of non-polyethylene low-molecular weight components, as the tapes do not require the presence of a finish.
