Scope

Main Technical Content: 1. Project Background Ultra-high molecular weight polyethylene (UHMWPE) fibers are made from UHMWPE with a viscosity-weighted average molecular weight of over 1 million, prepared by solution spinning. These high-performance organic fibers have a tensile strength of ≥25 cN/dtex and are characterized by low density, high specific strength, high specific modulus, acid resistance, alkali resistance, cut resistance, and UV resistance. With excellent comprehensive performance, they have been widely used in defense, marine engineering, personal protection, sports, and many other fields. Ultra-high strength polyethylene fibers, a sub-variety of UHMWPE fibers, are distinguished by their exceptionally high tensile strength and initial modulus. They exhibit tensile strengths of ≥45 cN/dtex and initial moduli of ≥1,700 cN/dtex, primarily used in bulletproof and explosion-proof products, such as bulletproof vests, helmets, inserts, and armor plates, serving as indispensable strategic materials for national defense. Given the recent instability in China's surrounding environment, the military's demand for lightweight bulletproof composites is expected to surge over the next 5-10 years. Establishing a standard for ultra-high strength polyethylene fibers will help ensure product quality and provide the military with reliable raw materials for bulletproof products. Currently, there are three industry standards and one national standard related to UHMWPE fibers in China: *Ultra-High Molecular Weight Polyethylene Filament*, *Colored Ultra-High Molecular Weight Polyethylene Fiber*, and *Ultra-High Molecular Weight Polyethylene Fiber for Cut-Resistant Gloves*. The proposed standard does not conflict with these existing standards and further refines their content. After its release, the new standard will provide a technical basis for research, production, and application. 2. Project Source In April 2022, Jiuzhou Xingji Technology Co., Ltd. applied f
