Ultrex
Data
Working load is based on static or moderately dynamic lifting/pulling operations. Instantaneous changes in load, up or down, in excess of 10% of line’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. Ultrex is to Yale Cordage Specification #YCI-UX-006.
Ultrex™ is a single-braid rope of 100% UHMPE fiber with our Maxijacket coating for superior abrasion resistance. Ultrex’s braid angles and twist level are designed to optimize break strength. With better bend-over-sheave resistance than other high-modulus fiber ropes, Ultrex has zero water absorption and maintains its flexibility even in freezing conditions.
Specific Gravity: 0.98
Dielectric Strength
The maximum allowable leakage for new dry Ultrex is 0.5 milliamperes at 60 K DC volts when tested in accordance with Yale Cordage Test Method DTP-185. Caution: Absorbed and entrained moisture or impurities will increase a rope’s conductivity dramatically.
Elastic Elongation
The colored area under the curve represents the rope’s energy-absorption capability.
