Choosing the right Dyneema® braid for your use

Understanding the characteristics of Dyneema® braids
Dyneema® ropes are hollow braids made of high modulus polyethylene fibers. Their characteristics vary depending on the assembly of the fibers and the treatments applied. Here are the key factors to consider:

• Twisting the wires:

o Before braiding, the threads are twisted (S or Z twist). This twist balances the fibers and improves abrasion resistance.


• The braiding step:

o A tight pitch makes the braid more elastic and resistant to abrasion, ideal for hooking systems.
o A long pitch reduces aspect ratio and increases stiffness, perfect for standing rigging.
• Pre-stretching:
o This process stabilizes the length of the rope under load, improves mechanical properties and reduces elongation.

• Sizing:

o A polyurethane bath protects the fibers against external attacks and facilitates splicing.
Applications and recommendations
• Dyneema® braids with short braiding pitch (tight):
o Ideal for attachments (lashings, loops, textile shackles) thanks to their resistance to abrasion and the strength of splices.

o Note: greater elongation due to the braiding pitch.
• Dyneema® braids with long braiding steps:
o Suitable for applications requiring a stable length under heavy load (standing rigging, strops).

o Offer excellent rigidity.
• Hot pre-stretched Dyneema®:

o An expensive but effective process for maximum stability under load.
o Perfect for standing rigging, with almost zero elongation and a stable length over time.

The choice of your Dyneema® braid will depend on what you want to use it for. Take into account the characteristics of each type of braiding and treatment to find the rope best suited to your needs.
