Rope Characteristic
Ultrex Plus is a double braid of Dyneema SK75 core, treated with Maxijacket
coating for enhanced toughness. Sleeved with high tenacity polyester.
Spliceable utilizing conventional high modulus splice technique, or the
new Yaletuck splice, which shortens the bury portion and minimizes the
length of the larger diameter associated with the splice. All strengths
shown are for spliced line.
Ultrex Plus is identified by green and yellow strands braided into the
sleeve structure. The date of manufacture is denoted by colored yarn
between the core and the sleeve. |

Dielectric Strength (Ultrex Plus™)
The maximum allowable leakage for new dry Ultrex Plus is 1.0 milliamperes
at 60K DC Volts when tested in accordance with Yale Cordage Test Method
DTP-185. Caution: Absorbed and entrained moisture or impurities will
dramatically increase a rope's conductivity.
