Dyneema®, the world’s strongest fiber

Dyneema® is a superstrong polyethylene fiber produced using a patented gel spinning process. This remarkable fiber is up to 15 times stronger than steel and, weight-for-weight, is 40% stronger than competing aramid fibers. It has high energy absorption and low elongation. Dyneema® floats on water, and is extremely resistant to abrasion, moisture, UV rays and chemicals. As a result, it has an almost unlimited range of applications, providing maximum strength and security for minimum weight.

DSM expands Dyneema® Production in Greenville, USA

Royal DSM N.V. today announces that it will invest to expand Dyneema® UD (UniDirectional
bullet resistant sheet) production by 25% in its Greenville, North Carolina (USA) manufacturing

Dyneema Perfect Cutting White, Rating 4342Spindles with Dyneema fibre are seen at the Dyneema plant in Heerlen November 12, 2007. To ensure that their cockpit doors were bullet proof, airlines turned to Dyneema, a thermoplastic that is 15 times stronger than steel but light enough to float on water. Dutch chemical company DSM had at one time almost abandoned Dyneema as a commercial product. Now DSM is hoping it can replicate the success of Kevlar, an aramid fibre made by DuPont Co.
