RIGBY offers a range of High Performance Cordage wtih Dyneema fiber from DSM. The ropemakers at Rigby were amongst the first in the world to work with Kevlar, again with Spectra, and are now proud to feature Dyneema.
Dyneema is built into Rigby rope and cordage when the design intent is to optimize high strength, low stretch, light weight, and negligible hysteresis (cold flow, or 'creep') (elongation over time under a sustained load).
Thus, Dyneema can be a useful fiber in ropemaking for high performance running rigging, lightweight lines that retain strength, and even replacement of wire rope or steel cable.
(The reader should note that notwithstanding its name, Dyneema is decidedly not used in Dynamic Ropes. While Dyneema can withstand high velocity strain rates, it does not dissipate a shock load in the manner in which a Dynamic Rope does. Do not confuse Dyneema with Dynamic).
DSM’s super-strong ultra-high molecular weight polyethylene (UHMwPE) fiber branded as Dyneema® offers maximum strength with minimum weight. This makes the number of possible applications virtually unlimited.
Dyneema® fiber is produced in a patented gel spinning process in which the fibers are drawn, heated, elongated, and cooled. Stretching and spinning leads to molecular alignment, high crystallization, and low density. Dyneema® has extremely long molecular chains that transfer load more effectively to the polymer backbone. So it's stronger at the same weight or lighter at the same strength than alternatives.
Dyneema® fiber is 15x stronger than steel at the same weight, with a tensile strength up to 43 cN/dtex. As well as its extraordinary strength, Dyneema® excels in cut and abrasion resistance and has a high resistance to chemicals and UV. Dyneema® fiber is so light that it floats on water and furthermore has a very high modulus (resistance against deformation).
