ISHI UHMWPE UD Fabrics are the most advanced ballistic protectionsolutions currently available on the market, having the best weight toballistic performance ratio. They are made with the lightest materialavailable: Ultra High Molecular Weight Polyethylene Fiber (UHMW-PE),capable of delivering high protection levels at a lower weight compared to traditional steel or other high performance ballistic materials. The panels feature exceptionally high multi-hit capability, providing the user an outstanding degree of safety if hit by multiple projectiles or fragments. Such fabrics combine Polyethylene fibers in a thermoplastic matrix that is capable of absorbing and dispersing high impact energy, such as energy from rifle shots. Each fabric layer has four plies of UD-Polyethylene fiber tapes cross-plied at 0° /90 °/0° /90° .
