New technologies strengthen deck rope
US based marine rope specialist Samson Rope Technologies Inc is launching the companys newest 12 strand stringing line, which incorporates Innegra-S fibre.
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 fibres gives ML-12 performance characteristics between traditional polyesters and high performance 100% Dyneema stringing lines.
Samson continues to bring new rope technologies into the marketplace. Recognising a void in the product line was the impetus for the research leading to Innegra-S. ‘We knew we had to consider fibres 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 fibre that would outperform traditional nylon and polyester, you had to leap into high performance fibres like HMPE, LCP, and aramids. Often 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 fibres 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’.
ML-12 offers lighter weight and higher strength at the same diameter as traditional polyester lines, so 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. ML-12 also offers improved elongation over traditional polyester lines.
‘This product will allow users to get more out of their existing equipment. In applications where the operator needs more versatility, ML-12 provides a new upgrade option, said Michael Quinn, sales director of Samson’s industrial division. ‘We believe ML-12 fills the performance gap between the traditional polyester lines and full HMPE products. Operators who need more than what polyester can provide, can now turn to ML-12.’
