PoBOn Cordage / Double Braided Polyester Sleeve Rope

PoBOn

Yale PoBOn™ is a double-braided rope consisting of a polyester sleeve covering an inner load bearing core of 100% Zylon&Reg; PBO. Zylon PBO (p-phe.nylene-2, 6-benzobisoxazole), manufactured by Toyobo of Japan*, is a rigid isotropic crystal polymer. It has outstanding tensile strength, high modulus, flame resistance, and thermal stability. PBO has a slight moisture gain in the range of 0.6% and is dimensionally stable against humidity.

* More information on Zylon fiber is available at the Toyobo web site: www.toyobo.co.jp

* 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% of the rope'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.
