UHMWPE fiber is an important national military material product, which is widely used in civil, industrial, safety protection, marine industry, etc. in the next 2-3 years, China may be the country with the largest production and sales volume in the world. At present, the domestic high-fiber production technology is basically mastered, and the quality has partially reached the international advanced level. Military supplies and national defense equipment have increased both at home and abroad. Affected by the current conflict between Russia and Ukraine and other situations, the global procurement of arms and materials has increased. At present, the domestic production capacity may be higher than 40000 tons. It is estimated that the domestic UHMWPE fiber production capacity will be 55000-60000 tons in the next year or two. Production capacity growth can not meet market demand: high fiber is not only used for national defense and military needs, but also for civil and industrial use. Steel wire rope was originally used for ship cables, but it may rust and pollute the marine environment. Many years ago, we began to explore the use of UHMWPE fiber to replace steel wire rope; High strength rope for outdoor sports, product hoisting rope, etc.: UHMWPE fiber products are light and have a large tensile force, and both civil and industrial use have increased significantly. In the future, China will be the country with the largest production and sales of high-fiber in the world, and it will not be limited to bullet proof, cutting proof, protective clothing, special clothing, rope net, etc. in the future, more fields will be developed. Based on its excellent performance, if there is no replacement of other new materials, I personally think it will be an important product in 5-8 years, with broad development prospects. Compared with the products of the same type, UHMWPE fiber has price advantages, and its penetration rate in various industries is constantly improving.
