  • Ropes having improved cyclic bend over sheave performance
    Publication number: 20070202331
    Abstract: An improved rope is formed from high tenacity fibers, preferably a blend of high tenacity polyethylene fibers with aramid fibers and/or liquid crystal copolyester fibers. The fibers and/or the rope are coated with a composition comprising an amino functional silicone resin and a neutralized low molecular weight polyethylene. The ropes are useful in marine applications, such as in deep sea lifting, and have improved cyclic bend over sheave fatigue resistance.
    Type: Application

  • High tenacity polyolefin ropes having improved cyclic bend over sheave performance
    Publication number: 20070202328
    Abstract: An improved rope is formed from high tenacity polyolefin fibers, such as extended chain polyethylene fibers. The fibers and/or the rope are coated with a composition comprising an amino functional silicone resin and a neutralized low molecular weight polyethylene. The ropes are useful in marine applications, such as in deep sea lifting. The ropes have improved cyclic bend over sheave fatigue resistance.
