Yale PoBOn is a double braided rope consisting of a polyester sleeve covering an inner load-bearing core of 100% Zylon® PBO. Zylon PBO poly
(p-phenylene-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 some moisture gain in the range of 0.6%, slightly greater than polyester, and is dimensionally stable against humidity.
Yale PoBOn is identified by a single black and a single red strand separated by four white strands, braided into the sleeve.

All high modulus fibered ropes have low stretch and little tolerance for shock loads. It’s ill advised to select a high strength rope in an attempt to solve shock loading problems.
The coloured area under the curve represents the rope’s energy absorption capability.
