Ultrex - 3/4" 12-Strand Single Braid
Ultrex is a 12-strand single braid of Ultra High Molecular Weight Polyethylene (UHMWPE) fiber from DSM Protective Materials and enhanced with Yale’s Maxijacket High Performance coating, which supplies superior abrasion resistance. Ultrex’s braid angles and twist level are designed to optimize break strength and keep stretch low.
 
UHMWPE is the most forgiving high-modulus fiber, giving better sheave-cycling capabilities than other high-tech fibers. Ultrex has zero water absorption and maintains its flexibility even in freezing conditions. As is the case for most Yale ropes, the strengths shown in the charts are for spliced ropes.

    * 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.

    Dielectric Strength: The maximum allowable leakage for clean, dry Ultrex is 75 micro-amperes when tested at 100kV per Yale Method 712-1701 Rev 1 “Routine Production Test.” Absorbed and entrained moisture or impurities will increase the rope’s conductivity dramatically.
