Made by DSM high performance fibers, Dyneema is the strongest fiber in the world.

Dyneema is a super-strong 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. ("From DSM’s website")
