Rope Characteristics

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.

* Knots and abrupt bends significantly reduce the strength of all ropes and lower maximum working load.
** Working load is based on static or moderately dyanmic lifting/pulling operations. Instantaneous changes in load, up or down, in excess or 10% of the rope’s related 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.

Rope Details

Fiber Type: Vectran LCP (Liquid Crystal Polymer), Polyester Sleeve
Elongation at WL: 0.5%
Elongation at Ult Break: 2.6 – 3.1%
Specific Gravity: 1.40 g/cc
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.”
Shock Loads: All high modulus fibered ropes have low stretch and little tolerance for shock loads. It’s ill advised to select a high strength rope in an attempt to solve shock loading problems.
