Global And China UHMWPE Fiber Industry Status

Sep 28, 2020

Ultra-high-molecular-weight polyethylene fiber, para-aramid fiber, and carbon fiber are also known as the three high-tech special fibers in the world today. They have high strength, high modulus, light weight, bulletproof, stab-resistant, cut-resistant, good seawater resistance, and chemical resistance. Corrosion, UV resistance, high abrasion resistance, low temperature resistance and other significant advantages, are widely used in national defense and military industry, aerospace, safety protection, engineering construction, marine fishery, civil textiles and other fields. At present, my country has become the world's largest producer and exporter of ultra-high molecular weight polyethylene fibers. The scale of the industry continues to grow, product quality continues to improve, and application areas continue to expand. It has broken the long-standing foreign technology monopoly and product ban.

The global ultra-high molecular weight polyethylene fiber is developing rapidly. The ultra-high molecular weight polyethylene industry with a production capacity of 65,000 tons in 2019 is developing very rapidly. In the 1930s, someone first proposed the basic theory of ultra-high molecular weight polyethylene fiber, 1983 Japan adopted a new technology to facilitate the industrialization of ultra-high molecular weight polyethylene fibers; and my country did not make ultra-high molecular weight polyethylene fibers a high-tech project of national scientific and technological development until 2001. Preliminary statistics show that the global UHMWPE fiber production capacity has continued to increase from 2015 to 2019. In 2018, the global UHMWPE fiber production capacity has increased significantly, with a total production capacity of 58,900 tons. In 2019, the global UHMWPE fiber production capacity reached 64,600 tons. The development and application of ultra-high molecular weight polyethylene fiber in Europe, America and other regions was earlier, and the average annual growth rate was small at first, about 5%. In recent years, due to conflicts around the world and increased awareness of national security protection, industries such as military equipment and security protection have developed rapidly, increasing the global demand for high-strength, high-performance and other ultra-high molecular weight polyethylene products. In 2019, the global ultra-high The demand for molecular weight polyethylene fibers reached approximately 86,000 tons.

Product application: both military and civilian

Military and aerospace fields

Utilizing its high-strength and wear-resistant protective performance, it is used in armored vehicle protective panels, tank protective linings, bulletproof helmets, shields, body armor, lightning protection boots, riot blankets, cut-resistant gloves, light composite armor, battlefield hospitals, battlefields Tents and other aspects.

Using its low dielectric constant, low dielectric loss, high sonar transmittance, etc., it is used in antenna fairing, missile cover, radar protective shell cover, etc.

Utilizing its light weight and high strength performance, it is applied to military ropes such as warships and armored vehicle cables and towing ropes, mine mooring ropes, parachute ropes, etc.

Utilizing its high strength, impact resistance, light weight and other properties, it is used in aircraft wingtip structures, spacecraft structures, buoy parts, UAV shells, and special umbrella materials.

Civilian field

In recent years, the application of my country's UHMWPE fiber in the field of civilian products has been greatly expanded, and the product structure has become more reasonable. In 2018, my country's total UHMWPE fiber consumption was 13,365 tons, of which 3320 tons were used in the rope and net field (24.8%), 4945 tons in the glove field (37.0%), and 3,530 tons in the bulletproof protection field (26.4%) ), 1570 tons (accounting for 11.8%) in the weaving field.

Utilizing its light weight, high strength, wear resistance, corrosion resistance, UV resistance and other properties, it is used in negative force ropes, heavy-duty ropes, salvage ropes, towing ropes, sailing ropes and fishing lines, including supertankers, marine operating platforms Fixed anchor ropes for lighthouses, etc.; used in marine fishing trawls, large-scale marine aquaculture cages; used in engineering construction ropes, safety belts, safety nets, home escape ropes, etc. It can also be used as a reinforcing agent in materials, such as adding ultra-short fibers to concrete to improve the seismic and impact resistance of concrete; using its biocompatibility and other properties, adding ultra-high molecular weight polyethylene fibers to artificial bone joints Enhance the strength and wear resistance of artificial joints.

The domestic UHMWPE fiber industrialization time is late, but it has developed rapidly. After entering the 21st century, my country has increased the industrialization of high-tech fibers. Especially since 2007, the National Development and Reform Commission has established a special support plan for high-tech fibers, and the scale of ultra-high molecular weight polyethylene fibers has increased from 100 tons to 1,000 tons. After ten years of rapid growth, my country has become a global ultra-high molecular weight polymer. Large producer of ethylene fiber. In 2019, the total production capacity of my country's ultra-high molecular weight polyethylene fiber industry was about 41,000 tons, accounting for more than 60% of the total global production capacity.
