Since 2013, the executive leadership selects 14–16 high performing, high potential associates each year to participate in the NextGen leadership development program. Dyneema® began as an ultra high molecular weight polyethylene (UHMPE fiber). We have completed a water risk evaluation of our manufacturing locations to identify which of them may be impacted by future water scarcity issues. 28% of facilities are in areas currently classified by the World Resources Institute Aqueduct Water Risk Tool as being extremely high or high for baseline water stress.
