Polydyne is a high strength double-braided rope incorporating a polyester sleeve over a nylon core. Polydyne maximizes load sharing between core and sleeve, yielding extremely high strength and high working energy absorption capacity. Nylon supplies give and polyester abrasion-resistance, and a willingness to cycle to a high percentage of break. Polydyne is identified by two green strands separated by a white strand braided into the cover of the rope.
Polydyne does virtually everything Double Esterlon does, but allows you to drop bigger wood, increasing productivity. Polydyne has a much higher working energy absorption meaning you can do more to the rope without damaging it.
The cover of this double braid is identical to our Double Esterlon, right down to the tree grade Maxijacket coating, the toughest in the industry. The secret is all in the core which in the case of Polydyne is high tenacity tire grade nylon.
Nylon provides the energy absorption advantage and allows the rope to stretch more in its early load cycle.
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. Polydyne is made to Yale Cordage Specification #YCI-PD-012
