Crystalyne is a double-braided rope constructed with an inner load-bearing core of Vectran Liquid Crystal Polymer (LCP) and has a tough polyester outer sleeve. LCP is more tolerant of bending than other high-modulus fibers and is not as affected by overloading.
Crystalyne exhibits more tension cycles to higher percentages of break than all our other high-modulus offerings. Unlike ultra-high-molecular-weight polyethylene (UHMPE) ropes, LCP fiber has little or no tendency to creep and can be used to hold tight tolerances in rope assemblies.
Vectran is hydrophobic, meaning it cannot absorb water. This rope is spliced using the same technique as our Maxibraid Plus, resulting in a termination that finishes shorter than conventional splice techniques and remains supple.
Crystalyne was one of the products selected to suspend the 40-ft.- diameter acrylic vessel filled with $225 million of heavy water at the Sudbury Neutrino Observatory (sno.phy.queensu.ca) and has been in service over 10 years, without movement.
Crystalyne is used in sailboat racing for halyards, sheets, guys and control lines.

* Knots and abrupt bends significantly reduce the strength of all ropes and lower the 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 constitute hazardous shock load and would void the normal working-load recommendation. Consult Yale Cordage for guidelines for working loads and the safe use of rope.
Green working 187 ft. lbs./lb.
Red ultimate 3,403 ft. lbs./lb.
Specific Gravity: 1.40
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 100kV per Yale Method 712-1701 Rev 1 "Routine Production Test."
