The flexible long-chain structure in XINGI ? UHMWPE fiber can quickly disperse the impact energy of bullets to a larger area, thereby reducing the depression depth of body armor and reducing non-penetrating injuries caused by impact. The body armor made of UD fabrics of different specifications is soft and comfortable, light and fit, and has a remarkable bulletproof effect, which can meet the domestic GA141-2010 standard and Americans NIJ bulletproof standard.
