BHP Armor Aramid XP™  Uni-Directional (UD) para-Aramid fabrics are used in a wide spectrum of ballistic protection applications. Such fabrics combine para-Aramid fibers in a flexible thermoplastic film matrix with adhesive that is capable of absorbing and dispersing high impact energy, such as energy from rifle shots.  The para-aramid fiber is lightweight and  extraordinarily strong, with 5 times the strength of steel on an equal-weight basis.
