Crystalyne - 1 Pages

  1. P. 1

Catalogue excerpts

Crystalyne is a double braided rope con- structed with an inner load bearing core of Vectran™ Liquid Crystal Polymer (LCP). Crystalyne has a tough polyester outer sleeve, protecting the inner strength member. LCP is more tolerant of bending than other high modulus fibers. It is not as affected by overloading, and exhibits more tension tension cycles to higher percentages of break than all our other high modulus offerings. Unlike UHMPE ropes, LCP fiber has little or no tendency to creep and can be used to hold tight tolerances in rope assemblies. In fact, Crystalyne was selected to suspend the 40-ft. diameter acrylic vessel, filled with $3 billion of heavy water at the Sudbury Neutrino Observatory (sno.phy.queensu.ca) and has been in service over 10 years, without movement. Vectran is hydrophobic meaning it cannot absorb water. This rope is spliced using the same technique as our Maxibraid Plus resulting in a termina- tion which finishes shorter than conventional splice techniques and remains supple. Average Spliced Break Strength* Minimum Spliced Break Strength* * Knots and abrupt bends significantly reduce the strength of all ropes and lowers maximum working load. ** Working load is based on static or moderately dynamic lifting/pulling operations. Instantaneous changes in load up or down, in excess of 10% of the rope's rated working load constitutes hazardous shock load and would void normal working load recommendation. Consult Yale Cordage for guidelines for working loads Energy Absorption The colored area under the curve represents the rope's ability to do "work" and is expressed in foot-pounds per pound of rope in tension. ■ Green working 187 ft. lbs./lb. Dielectric Strength: Crystalyne's core of LCP is hydrophobic so its lack of core moisture gain is an advantage as is its high melt point of 620°F (325°C). The polyester sleeve governs the leakage which is 100 Micro Amperes at 90 KV reference ASTM 1701-05 "Routine Production Test".
