Double Esterlon™
Rope Characteristics
Double Esterlon is a double braided rope constructed of Honeywell’s unique type 1W81 high tenacity cordage finish polyester. It offers low stretch, high strength, and excellent wear life and dielectric strength.
Double Esterlon is identified by two adjacent green strands braided into the cover structure. The date of manufacture is denoted by coloured yarn between the core and the sleeve.

Dielectric StrengthThe maximum allowable leakage for new dry Double Esterlon™ 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. Double Esterlon is made to Yale Cordage Specification #YCI-DE-022 |
