Cortland Plasma® 12 Strand

Plasma® 12 strand is the highest strength synthetic rope available. Plasma® 12 strand is manufactured from High Modulus Polyethylene (HMPE) that has been enhanced by Cortland’s patented recrystallization process. This process is especially effective in medium to large diameter ropes where strengths are more than 50% higher and creep is significantly less than that of standard Spectra® 12 strand.

Plasma® 12 strand is delivered standard with a polyurethane finish and is easily spliced using a simple lockstitch type splice, 4-3-2 or 5-4-3 Tuck Splice. Its soft, torque free braided construction provides easy handling.

* Value based on data supplied by the fiber manufacturer for new, dry fiber

Tensile Strengths are determined in accordance with Cordage Institute 1500.2. Test Methods for Fiber Rope. Minimum Tensile Strength (MTS) published assumes spliced eye terminations at each end of the rope. Weights actually calculated at linear density under stated preload (200d2) plus 4%. Diameter and circumference size published is nominal and reflects rope size after loading (10 cycles) to 50% of MTS. Spectra® is a Trademark of Honeywell.
