Revolutionary new high-strength guy ropes using Dyneema Max Technology
Mastrant M ropes using new Dyneema Max Technology (by DSM) maximizes the scope of the world’s strongest fiber. Mastrant is pioneering the use of high performance synthetic rope in permanently loaded applications. Designed specifically for mooring production facilities in deep waters, DSM’s new ‘ultra-high strength at low weight’ Dyneema DM20 fiber delivers unrivalled rope strength, stiffness, durability and longevity.
Laboratory tests demonstrate that ropes made from DM20 fiber retain the property characteristics of Dyneema, even under long-term high tensions. Critical behavioral qualities, such as high static strength and stiffness, exceptional abrasion, fatigue and creep resistance enable a smaller, lighter rope to deliver improved performance and operational benefits. Dyneema Max Technology performs significantly better than SK78 on creep and thus is another step change versus all other HMPE (high-modulus polyethylene). At the same time it keeps the good properties of Dyneema fiber, which are appreciated by many users. The breakthrough product now offers all the benefits of ropes made with Dyneema also to the markets of permanently loaded applications like guying of towers, masts and antennas.
- Construction: Double braided rope
- Core: 100% Dyneema DM20, braided
- Inner cover: Polyester staple (only on ropes with diameters from 6 mm and up)
- Outer cover: Polyester 12, 16, 24 or 40 (depending on the diam.)
- Safe temperature: -110 °C (-166 °F) to 90 °C (194 °F)

Excellent for guy rope that you want to be permanent out in the weather. I have some that's over 10 yrs old holding up dipoles in the trees. Its impressive to say the least!! I use the 2mm line for everything.

I have used this type of "rope" as guy line exposed to the elements for years with no issues.
