Cortland Plasma® 12×12 Strand Rope

Plasma® 12×12 is a 12-strand braided rope in which each of the 12 strands is, in turn, a 12-strand rope, or braided primary strand. Plasma is manufactured from High Modulus Polyethylene (HMPE) that has been enhanced by Cortland’s patented recrystallization process.

This patented construction addresses the most critical properties of the fibers to provide a very high strength translation efficiency for larger ropes. This design allows for long lay lengths, making rope that is more flexible for bending applications, easy to inspect, and can be quickly spliced using standard 12 strand splicing techniques. Plasma 12×12 is supplied with our standard polyurethane finish, although other coatings can be applied to suit specific applications.

Size: Diameter and circumference are nominal. A new unused rope in relaxed state will measure larger; loading and use compacts ropes, sets splices and lessens rope size. This is especially prevalent in sizes above 4″ diameter. Published nominal sizes from 4-1/8″ and larger represent stabilized or preloaded size.

Weights: Published weights of sizes 1-5/8″– 4″ diameter are calculated at linear density under stated preload (200d²) plus 4%. For this chart, sizes 4-1/8″–8-1/4″ diameter represent un-cycled, (non-stabilized) weights.

Tensile Strengths: Tensile strength determined in accordance with Cordage Institute 1500 Test Methods for Fiber Ropes and ISO 2307.
