Dyneema (HMPE) Rope Specifications

Dyneema (HMPE) rope, made from ultra-high-molecular-weight polyethylene, is one of the strongest and lightest synthetic ropes available. It’s up to 15 times stronger than steel by weight, floats on water, and offers excellent resistance to abrasion, UV degradation, and chemicals.

We supply Dyneema (HMPE) ropes suitable for marine, off-road, recovery, lifting, and high-performance industrial applications.

What is Dyneema (HMPE) Rope?

Dyneema (HMPE) is a high-modulus polyethylene fibre known for its exceptional strength-to-weight ratio. It is commonly used in critical applications where low weight and high strength are essential, such as winching, sailing, and tactical equipment.

Note: Always allow for a safety margin when selecting rope. Splicing can reduce the overall break load by up to 10%.

Key Features of Dyneema (HMPE) Rope

• Exceptional strength-to-weight ratio
• Lightweight and floats on water
• Very low stretch under load
• Highly resistant to UV, abrasion, and most chemicals
• Minimal water absorption
• Working temperature range: –40°C to +70°C

Uses for Dyneema (HMPE) Rope in Marine, Recovery & Rigging

• Marine and sailing – winch lines, tow ropes, anchor lines
• Off-road recovery – safer and lighter than steel wire
• Lifting and rigging – synthetic slings, lifting lines
• Military and defence – field lines and tactical gear
• Rope access and rescue – hauling lines and safety ropes

How to Splice and Handle Dyneema (HMPE) Rope Safely

For best strength retention, always splice rather than knot. Use proper splicing tools or fids. Dyneema’s slick surface means knots can slip or reduce strength significantly.
