Samson, specialist in performance cordage, is launching Samson’s newest 12-strand stringing line, incorporating Innegra-S fiber. ML-12 is Samson’s newest 12-strand stringing line, blending Innegra-S, a high modulus polypropylene (HMPP), and Dyneema, a high modulus polyethylene (HMPE). This blend of fibers gives ML-12 performance characteristics between traditional polyesters and high-performance 100% Dyneema stringing lines.
“We knew we had to consider fibers that were unfamiliar to the rope industry in order to achieve our goals,” said vice president of research and development, Dr. Rafael Chou. “Historically, if you wanted a fiber that would out perform traditional nylon and polyester, you had to leap into high-performance fibers like HMPE, LCP, and aramids. Oftentimes this was not the best solution because the degree of performance improvement might be overkill for the application, making it too expensive. We set out to find the missing link in synthetic fibers for rope making. That’s when we found InnegraTM-S.” A high modulus polypropylene (HMPP), InnegraTM-S, when blended with HMPE, creates a line that is lighter and stronger than nylon and polyester, and comfortably fits the mid-point in performance and price.
Because ML-12 offers lighter weight and higher strength at the same diameter as traditional polyester lines, it can be used on existing equipment for heavier pulls, or it is possible to downsize the line on equipment to pull the same load and store longer lengths on the reel.
