DSM Dyneema's Dyneema HB80 is a unidirectional (UD) composite that meets the joint US Army and Marine challenge to increase the fragmentation performance by at least 35 percent of advanced combat helmets. Dyneema HB80 also has the potential to provide law enforcement SWAT units with helmets offering existing protection at half the current weight. Dyneema HB80 addresses the requirements for Enhanced Combat Helmet (ECH), a joint program of the US Army and Marines. Under the pre-launch prototype name Dyneema® X31, the product has undergone extensive ballistic and secondary-property testing by several helmet manufacturers. In testing, helmets made with Dyneema HB80 have demonstrated a minimum of 35 percent increase in fragmentation performance when compared to the helmets currently used by the US armed forces.
