DTM Composite Double Braid
Dyneema® SK75 Core, Polyester Jacket, Double BraidDTM 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.
