Dyneema Extra Information
Invented 1979 in the Netherlands and in commercial production since 1990. Dyneema® is both the worlds strongest fibre and the only HMPE fibre scientifically engineered to overcome abrasion, bending fatigue, compression, and creep fatigue. It is up to 15 times stronger than steel weight for weight.
Technical Specification on Dyneema

Abbreviation: HMPE (Ours is DY)
Specific Gravity: 0.96 Floats
Resistance to Acid: No reaction
Resistance to Alkali: Very resistant
Resistance to Solvents: Minimal reaction
Resistance to Heat: Up to 70°C Short exposure (Low:-85°C)
Resistant to UV: Excellent
Resistance to abrasion: Excellent
Affected by Moisture: No
Stretch: Very Low (3.8% at break). Creep: At high loads
Knot holding: Fair but weakens the rope by up to 70%
Washing temperature: 30°C
Approximate Melting Point: 150°C
This heat stretched 100% Dyneema rope will provide the optimum breaking load with the lowest possible stretch. Coupled with its excellent abrasion resistance, low weight and easy spliceability makes this line a perfect choice for replacing wire halyards. Our D-Pro has a non-reflective matt black surface making it also a useful rope for use in the entertainments industry.
Technical Specification: Coated Dyneema SK78. Working Stretch less than 1%. UV Stabilised.
- Exceptional strength
- Very low stretch
- Very easy to splice
- Difficult to cut
- Poor resistance to heat - avoid heavy winching
- Will creep under prolonged load
Main Uses Wire rope replacement. High performance halyards. Non-stretch control cables. Motorised track hauling lines. Rigging screw replacement lashings. Soft shackle construction. Non-whiplash towing applications
