Yale Polydyne Rigging Rope - a step up from Yales Double Esterlon
Yale Polydyne does virtually everything that Yale Double Esterlon does, but allows you to drop bigger wood, increasing productivity. Polydyne has a much higher working energy absorbtion, meaning you can do more to the rope without damaging it.
The polyester cover of Polydyne is identical to Double Esterlon. The secret is all in the core which in the case of Polydyne is high tenacity tyre grade nylon. Nylon provides the energy absorbtion advantage and allows the rope to stretch more in its early load cycle.
For example, the minimum spliced break strength of 16mm Polydyne is 9,100Kg compared to 16mm Double Esterlon at 6,100Kg, giving you a 49% increase in the maximum work load.

* 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.
