CRYSTALYNE.

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.

* 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

and safe use of rope.

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".
