Rope Characteristic
Yale Crystalyne is a double braided rope consisting of a polyester sleeve
covering an inner load bearing core of LCP (Liquid Crystal Polymer).
LCP, manufactured by Celanese, is the latest "breakthrough" fiber.
Liquid Crystal Polymer is more tolerant of bending than other high modulus
fibers. Unlike Spectra, LCP thrives at high loads and doesn’t have
a creep to failure mode.
Yale Crystalyne is identified by a single black and a single yellow strand
separated by four white strands, braided into the sleeve. |

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.
Elastic Elongation (Crystalyne™)
The colored area under the curve represents the rope's energy absorption
capability.
 Green
working 242 ft. lbs/lb
 Red

Dielectric Strength (Crystalyne™)
LCP is a hydrophobic fiber giving it high dielectric strengths equal
to Maxibraid Plus.
LCP also has high temperature melt point (621ºF) similar to Aramid
Fibers. |
