Scope

Main Technical Content: 1. Project Background Ultra-high molecular weight polyethylene (UHMWPE) fibers are prepared by solution spinning from UHMWPE with a viscosity-weighted average molecular weight of over 1 million. These high-performance organic fibers exhibit tensile strength ≥ 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 applied in national defense, marine engineering, personal protection, sports, and other fields. Ultra-high strength polyethylene fibers, a sub-type of UHMWPE fibers, are distinguished by exceptionally high tensile strength and initial modulus. With tensile strength ≥ 45 cN/dtex and initial modulus ≥ 1,700 cN/dtex, they are primarily used in bulletproof and explosion-resistant 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 reliable raw materials for military bulletproof products. Currently, there are three industry standards 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*, as well as a national standard *Ultra-High Molecular Weight Polyethylene Fiber*. The proposed standard does not conflict with these existing standards and further refines their content. After its release, it will provide a technical basis for research, production, and application. 2. Project Origin In April 2022, Jiuzhou Xingji Technology Co., Ltd. applied fo
