Dyneema
Dyneema is a polyethylene produced by DSM's patented gel spinning process. Dyneema is 15 times stronger than steel on a weight-for-weight basis, twice as strong as Aramid fiber.
Dyneema UD (Dyneema based unidirectional) sheets are for high-velocity ballistic protection. Dyneema is light enough to float on water, exhibits superior resistance to chemicals, water and UV light.
