What is UHMWPE UD Unidirectional Fabric? Full Performance Introduction

UHMWPE UD unidirectional fabric is high-performance ballistic raw material made from ultra-high-molecular-weight polyethylene fiber with special resin matrix. Fibers are arranged in single direction and laminated in 0°/90° cross-ply structure to disperse bullet impact energy efficiently.

This material features ultra-light weight and excellent bullet-stopping capacity. Its density is lower than aramid, helping reduce total weight for soft body armor, ballistic helmet and hard armor plates. However, UHMWPE performs poorly under high-temperature environment, long-term temperature above 80℃ will cause gradual performance degradation.

Our UHMWPE UD fabric is supplied in continuous roll form, supporting hot-press processing for various ballistic protective end products.
