Due to its numerous excellent properties, ultra-high molecular weight polyethylene fibers have shown great advantages in the high-performance fiber market, including mooring ropes in offshore oil fields and high-performance lightweight composite materials. They play a crucial role in modern warfare, aviation, aerospace, maritime defense equipment, and other fields.

In terms of national defense.

Due to its excellent impact resistance and high energy absorption, this fiber can be used in military applications to make protective clothing, helmets, and bulletproof materials, such as armor plates for helicopters, tanks, and ships, radar protective casings, missile covers, bulletproof vests, stab proof vests, shields, etc. Among them, the application of bulletproof vests is the most eye-catching. It has the advantages of softness and better bulletproof effect than aramid, and has now become the main fiber occupying the US bulletproof vest market. In addition, the specific impact load value U/p of ultra-high molecular weight polyethylene fiber composite materials is 10 times that of steel, and more than twice that of glass fiber and aramid. Bulletproof and riot helmets made of resin composite materials reinforced with this fiber have become substitutes for steel helmets and aramid reinforced composite helmets abroad.

Civil aspect
(1) The application of ropes and cables: Ropes, cables, sails, and fishing gear made of this fiber are suitable for marine engineering and were the initial use of this fiber. Commonly used for negative force ropes, heavy-duty ropes, salvage ropes, towing ropes, sailboat ropes, and fishing lines. The rope made of this fiber has a fracture length of 8 times that of steel rope and 2 times that of aramid under its own weight. This rope is used as a fixed anchor rope for super oil tankers, ocean operation platforms, lighthouses, etc. It solves the problems of corrosion, hydrolysis, and UV degradation caused by steel cables and nylon and polyester cables in the past, which lead to a decrease in cable strength and breakage, and require frequent replacement.
(2) Sports equipment and supplies: Safety helmets, skis, sail boards, fishing rods, rackets and bicycles, gliders, ultra lightweight aircraft components, etc. have been made on sports equipment, and their performance is better than traditional materials.
(3) Used as a biomaterial: This fiber-reinforced composite material is used in dental support materials, medical implants, and plastic sutures. It has good biocompatibility and durability, high stability, and will not cause allergies. It has been clinically applied. It is also used in medical gloves and other medical measures.
(4) In industry, this fiber and its composite materials can be used as pressure vessels, conveyor belts, filtering materials, automotive buffer plates, etc; In terms of architecture, it can be used as a wall, partition structure, etc. Using it as a reinforced cement composite material can improve the toughness of cement and enhance its impact resistance.
