Polydyne - 1 Pages

  1. P. 1

Catalogue excerpts

Polydyne is a double braided rope which utilizes a polyester sleeve over a nylon core. Despite the dissimilar stretch characteristics of these fibers, Yale engineers have produced constructions where both fibers contribute. The resulting rope has high breaking strength and more stretch in its working load range, which in many applications is a plus. Polydyne is up to taking more dynamic abuse without being degraded prematurely. Take special note of the working energy absorption rating which is the amount of energy a rope absorbs before reaching its working load. The ultimate energy absorption of this rope is also correspondingly high. All this and a tough polyester jacket make this a long wearing rope with extraordinary dynamic capabilities. Average Spliced Break Strength* Minimum Spliced Break Strength* * Knots and abrupt bends significantly reduce the strength of all ropes and lowers 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 percent of the rope's rated working load constitutes hazardous shock load and would void normal working load recommendation.
