Braid Optimized for Bending (BOB®) 12×12

Back to top

BOB® 12×12 Strand is a high strength, low elongating single braided rope construction with excellent long term creep resistance and superior cyclic fatigue performance, especially in bend-over-sheave applications. In the 12×12 strand construction, each strand consists of a smaller 12 strand rope produced using a proprietary blend of fibers. This design maximizes the strength of the fiber while allowing damaged rope strands to be removed and replaced if necessary. BOB® 12×12 Strand comes standard with a specially formulated coating that is designed to maximize the rope’s durability in bending situations.

BOB 12×12 Strand is easily spliced using a lockstitch type splice, Brummel splice, 4-3-2 or 5-4-3 Tuck splice. The soft, torque free braided construction provides easy handling.

DTM Composite Double Braid

Back to top

DTM Composite Double Braid ropes have very high strength, are firm with a round profile, and have extremely low stretch. These durable, torque free synthetic ropes are excellent for replacing steel wire rope in winch applications and are designed to withstand drum compression. DTM ropes can be used in multiple applications such as vessel mooring lines for Articulated Tug & Barges (ATB’s), Gilson winch lines used in commercial fishing, as well as helicopter long lines.

DTM Double Braid ropes are constructed with a braided Plasma® HMPE fiber core. This core is encased in a tightly braided jacket of a Polyester fiber that offers high abrasion and durability. The final construction of core and cover work in balance to provide excellent service life.

* DTM Composite ropes can also be designed with materials other than HMPE for jacketing depending on application. Linear density & external fiber properties will change depending on jacketing material but the strength will remain the same on a per size basis. Please contact Cortland for further information.

DTM Composite Double Braid

G/T Composite Double Braid

Back to top

G/T Composite ropes provide high strength, low stretch and superior abrasion resistance in a firm round jacketed construction. The ropes are constructed with a braided Plasma® core. This core is encased in a tightly braided jacket of a new generation HMPE fiber that offers the highest abrasion resistance and durability.* G/T Composite ropes can be used in mooring applications where a very high strength, firm and round torque free rope is desired.

G/T Composite can also be used in commercial fishing as wire rope replacement and helicopter longlines. These ropes are available with a polyurethane finish in clear or any of six colors, and are designed to withstand drum compression on mooring winches.

* GT Composite ropes can also be designed with materials other than HMPE for jacketing depending on application. Linear density & external fiber properties will change depending on jacketing material but the strength will remain the same on a per size basis. Please contact Cortland for further information.

Plasma® HiCo 12×12 Tech Sheet

Plasma® LoCo 12 Strand

Back to top

Plasma® LoCo 12-Strand retains all of the features and benefits of standard Plasma ropes with the added characteristic of a reduced coefficient of friction coating. The enhanced coating provides improved UV resistance and reduces internal heat build-up and abrasion associated with constant tension-tension fatigue, relative movement between the rope and fixed surfaces, and during cyclical bending.

Cortland’s proprietary LoCo coating process ensures superior adherence to the braided Plasma rope, providing an effective bond for increased service life and wear especially in wet environments. The LoCo design can be quickly spliced using Cortland’s recommended splicing techniques for low coefficient of friction ropes.

Cortland’s Plasma 12-Strand ropes are the culmination of 25+ years of engineering expertise in the HMPE industry. Our dedication to providing customers with industry-leading synthetic line is and always has been the goal. Our continued innovation and unwavering desire are to provide the strongest and most reliable product available.

Cortland’s proprietary LoCo coating process ensures superior adherence to the braided Plasma rope, providing an effective bond for increased service life and wear especially in wet environments.

Plasma® LoCo 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. This construction addresses the most critical properties of the fibers to provide very high strength translation efficiency for larger ropes. This design provides superior snag resistance compared to other 12-Strand designs which is important when dragging the rope.

Toro™ 12×12

Back to top

Toro™ 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. Toro is manufactured from high tenacity High Modulus Polyethylene (HMPE).

This 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. Toro 12×12 is supplied with our standard polyurethane finish, although other coatings can be applied to suit specific applications.

Zylon® / PBO

Back to top

Zylon® Polybenzyloate (PBO) is a rigid-rod isotropic crystal polymer that is spun by a dry-jet wet spinning process.

Zylon / PBO was first developed in the 1980’s and studies suggest the mechanical strength to be more than two times stronger than any other commercialized synthetic fiber. It is also the first organic fiber whose cross-sectional strength outperforms both steel and carbon fiber. Its high creep resistance and tensile strength potentially makes Zylon / PBO as one of the strongest synthetic fibers in the overall fibers market.

The strength of ZYLON® / PBO decreases in the condition of high temperature and high humidity. To maintain its mechanical properties, the fiber should be stored free from exposure to light, high temperature and humidity.

The manufacturing costs involved with the production of Zylon / PBO are also very high, therefore PBO fibers are used mainly in demanding applications such as strength members in defense-application products.
