DSM Dyneema SB51 is the first of DSM Dyneema's new series of unidirectional (UD) material developed for use in ballistics vests. DSM Dyneema SB51 has been developed for use in ballistic vests that combine minimum weight with protection against handgun ammunition, fragments and knives.
Dyneema SB51 is made with ultra-high molecular weight polyethylene (UHMWPE) Dyneema fiber, as are its predecessors, the Dyneema SB21 and SB31. However, the Dyneema SB51 material demonstrates improvements up 20 percent for specific bullet and test specifications.
