Ultra-high molecular weight polyethylene (UHMWPE or UPE) refers to linear polyethylene with an average molecular weight of more than 1.5 million. It is also called high strength and high modulus polyethylene fiber. Ultra-high molecular weight polyethylene fiber, with carbon fiber and aramid fiber, is called the three high-performance fibers. It is the fiber with the highest specific strength and bullet proof performance among the industrial fiber materials. Due to its extremely high molecular weight, ultra-high molecular weight polyethylene has the comprehensive use performance incomparable to ordinary polyethylene and other engineering plastics, and is called "amazing plastic" by many European and American countries. UHMWPE fiber has excellent properties such as high strength and high modulus, impact resistance, wear resistance, chemical corrosion resistance, electrical insulation and light resistance. Its specific strength is equivalent to 15 times of high-quality steel wire, 1.8 times of carbon fiber, and 1.6 times of aramid fiber. It has an ultra-low elongation at break, high energy absorption rate, soft and easy to bend, and the density is smaller than water. It is widely used in national defense and civil industry. It is the strategic material of the powerful nation and the powerful army. It is widely used in many industries. It is the first choice for making bulletproof clothing, bulletproof helmets and protective armor.

Key application areas of UHMWPE fiber
01 national defense and military industry
UHMWPE fiber "as thin as paper, as hard as steel", the bulletproof and explosion-proof helmet made of UHMWPE fiber reinforced resin composite material has become a substitute for steel helmet and aramid fiber reinforced composite helmet.
Foreign bulletproof helmet and explosion-proof helmet made of UHMWPE fiber reinforced resin composite material has gradually replaced steel helmet and aramid fiber composite helmet.
With the improvement of national defense and military arms level, the demand driving force for UHMWPE fiber industry will be more and more.
02 aerospace field
In aerospace engineering, due to the lightweight, high strength and good impact resistance of the fiber composite material, it can be applied to the wing tip structure, spacecraft structure and buoy aircraft of various aircraft. The fiber can also be used as the deceleration parachute for space shuttle landing and the rope for suspending heavy objects on the aircraft, replacing the traditional steel cable and synthetic fiber rope, and its development speed is extremely rapid.
03 marine field
In the marine industry, UHMWPE fiber with its excellent performance has quickly become the main material of ropes and cables used at sea, mooring ropes of ships, ocean-going fishing nets and offshore aquaculture nets. The market demand to maintain strong growth, especially rope, cable and other rope net manufacturing, rope, cable made of UHMWPE, in the dead weight of the breaking length is much higher than steel rope and aramid fiber, and lighter than water, can float on the surface, and resistant to seawater corrosion and ultraviolet radiation, can ensure a longer service life. The future market demand will maintain strong growth.
04 sports equipment field
In the field of sports equipment, UHMWPE fiber can be made into helmet, ski board, sail board, fishing rod, racket and bicycle, gliding board, ultra-lightweight aircraft parts, etc., its performance is better than traditional materials.
05 medical and health field
In the field of medical and health, UHMWPE fiber reinforced composites for dental materials, medical implants and plastic suture, its biocompatibility and durability are good, and has high stability, will not cause allergies, has entered the clinical application. Can also be used for medical gloves and other medical equipment.
06 construction field
In the construction industry, UHMWPE fiber reinforced composites can be used for wall, partition structure, as reinforced cement composites can improve the toughness of cement, improve its impact resistance. UHMWPE fiber can also be used as building materials lifting rope, building safety net, hanging net, etc.
07 other fields of application In industrial applications, UHMWPE fiber and composites can be used as pressure vessels, conveyor belts, filter materials, automobile buffer plates, etc. Because of the excellent wear resistance and impact resistance of UHMWPE fiber and composites, they can be used in the manufacturing industry to make various mechanical parts such as gears, cam, impeller, roller, pulley, bearing, bearing bush, sleeve, shaft cutting, gasket, gasket, elastic coupling, screw and so on.
