Dyneema® Fiber

Simply the world’s strongest fiber

The Dyneema® Secret

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). Dyneema® is available in a wide range of titers (fiber thickness), from 50 to 6600 dtex, making the fiber suitable for many applications.

3 reasons to choose Dyneema®

High strength

Up to 15x stronger than steel and up to 40% stronger than aramids (weight for weight basis)

Lightweight

So light it floats on water

More Durable

Resistant to moisture, UV, chemicals

Dyneema® technology platforms

Dyneema® fiber is available in a wide range of grades and forms the basis for three technology platforms to serve a wide range of applications and industries. These platforms are Dyneema® Diamond Technology, Dyneema® Max Technology and Dyneema® XBO Technology.

Dyneema® Diamond Technology

Dyneema® fibers have long been the material of choice for cut resistant gloves. Building on this industry leading heritage, Dyneema® Diamond Technology continues to evolve to meet modern requirements and guarantee the best protected hands in the industry. Offering some of the most comfortable, dexterous and durable gloves available today, Dyneema® Diamond Technology ensures that worker hands stay safe throughout the glove’s lifespan.

Dyneema® Max Technology

Developed for use offshore, ropes with Dyneema® Max Technology outperform the alternatives, surpass industry standards for (deep water) permanent mooring solutions, and will outlast the operational life of the installation. Seven times stronger than steel wire rope, the fiber also opens the door to other applications where the strengths of Dyneema® are now no longer compromised by an excessive creep.

Dyneema® XBO Technology

Strong yet lightweight ropes made with Dyneema® XBO Technology not only outperform other synthetic ropes on bending performance, they also match or even outperform the bending performance of specialty steel wire rope. This makes ropes with Dyneema® XBO Technology ideal for applications where superior bending performance is required.
