Inserts made with Dyneema® UD provide protection against rifle threats, alone
or in combination with ceramics or steel. Dyneema® UD is unique in that it can
stop rifle rounds, such as NATO Ball and AK47 Mild Steel Core, on its own. In
combination with other materials, Dyneema® UD also provides protection against
armor-piercing bullets (e.g. NIJ level IV). All options have excellent
multi-hit capabilities. The UD construction makes backface deformation wider
and less deep, thereby minimizing blunt trauma effect.
