Marlow Dyneema Explained
Marlow at the forefront of the Dyneema Revolution
DTB Motor Services
Dyneema® is an UHMwPE (Ultra High Molecular weight Polyethylene) fibre developed by DSM in the Netherlands little over 20 years ago. An ingredient material in many of our ropes, Dyneema® is light weight and renowned as "The World's Strongest FibreTM". So what makes Dyneema® so special? High Strength: On a weight for weight basis, Dyneema® is 15 times stronger than steel wire.
Light Weight: Strength for strength, Dyneema® is 8 times lighter than steel wire. Dyneema® also has a Specific Gravity of 0.97 which means it floats in water. Water resistant: Dyneema® is hydrophobic and does not absorb water, meaning it remains light when working in wet conditions and is there also more durable.
Chemical resistance: Dyneema® is chemically inert, and performs well in dry, wet, salty and humid conditions, as well as other situations where chemicals are present.
UV Resistant: Dyneema® has very good resistance to photo degradation, maintaining its performance when exposed to UV light.
Ropes with Dyneema® are replacing steel wire in many varied applications and Marlow as ever are at the forefront of the Dyneema® revolution. Chief among these new applications is wire rope replacement on winches. Originally pioneered in the recreational 4x4 market, Marlow is now pioneering the use of Winch Lines with Dyneema® in the roadside recovery market and other industrial winching applications. The benefits of replacing steel wire with Marlow's Dynaline winch lines with Dyneema® are as compelling as they are for sailing
High strength: Weight for weight, Dyneema® is 15 times stronger than steel.
Light weight: Dyneema's light weight significantly improves the ease of handling winch ropes.
Floats: An obvious benefit when winching in water logged conditions or flooded environments.
Un-kinkable: Unlike steel wire, Dynaline will not kink and loose strength.
No splinters: Handling steel wire often results in wire splinters - no such issues with Marlow's Dynaline.
Overlapping: Steel wire will crush and loose strength if overlapped on a winch drum. Marlow Dynaline will not loose strength when overlapped or crushed.
No recoil: In the unlikely event of Dynaline breaking there is virtually no recoil, unlike steel wire where recoil is extremely dangerous. Extensive trials have also found that Dynaline winch lines with Dyneema® need to be replaced less frequently than steel wire. The ease of handling, increased safety and improved longevity of Dynaline winch lines are why more and more industries are making the switch.
