Polydyne™ is a high strength double-braided rope incorporating a polyester sleeve over a nylon core.
Despite the dissimilar stretch characteristics of these fibers, Polydyne™ maximizes load sharing between core and sleeve, yielding extremely high strength and high working energy absorption capacity. Available with Maxijacket Coating.
Specific Gravity: 1.24
DIELECTRIC STRENGTH
The maximum allowable leakage for new, dry, clean Polydyne™ is 500 Micro Amperes when tested at 90KV per ASTM 1701-05, “Routine Production Test”.
CAUTION Absorbed and entrained impurities will increase rope conductivity, DRAMATICALLY.

Work Load Limits are based on static or moderately dynamic lifting/pulling operations. Instantaneous changes in load, up or down, in excess of 10% of line’s Work Load Limit constitutes hazardous shock loading and would void normal Work Load Limit recommendations. See the engineering information found under "Product Resources -> Yale Cordage: Index of Engineering" and consult Yale Cordage for guidelines regarding Work Load Limits and safe use of rope. Knots and abrupt bends significantly reduce rope strength and lower Work Load Limits.
Double Esterlon™ is made to Yale Cordage Specification #YCI-DE-022. Polydyne™ is made to Yale Cordage Specification #YCI-PD-012. Splice Double Esterlon™ or Polydyne™ using Yale’s splicing document No. 10017200.
