UHMWPE Fiber

Performance profile:

UHMWPE-raw yarn, ultra-high molecular weight, high-strength high-modulus, molecular weight polyethylene, referred to as UHMWPE, also known as high-strength high-modulus polyethylene fiber, is currently the world’s fiber with high specific strength and specific modulus, and its molecular weight is between 1 million and 5 million. Fiber spun out of polyethylene.

Characteristic:

1. High strength and high modulus. The strength is more than ten times that of steel wires of the same cross-section, and the modulus is second only to carbon fiber.

2. The fiber density is low, and the density is 0.97g/cm3, which can float on the water surface.

3. Low elongation at break, great work at break, and strong ability to absorb energy, so it has outstanding impact resistance and cutting resistance.

4. Anti-ultraviolet radiation, anti-neutron and gamma rays, high specific energy absorption, low dielectric constant and high electromagnetic wave transmittance.

5. Chemical resistance, wear resistance, and long flex life.

Physical properties:

Density: 0.97~0.98g/cm3. It has a lower density than water and can float on water. Strength: 2.8~4N/tex. Modulus: 91~140N/tex. Elongation: 3.5% to 3.7%. The impact energy is nearly twice as high as that of para-aramid fiber, with good abrasion resistance and low friction coefficient, but the melting point under stress is only 145-160°C.

Application:

It is widely used in security protection, aviation, aerospace, navigation, electronics, weapons, shipbuilding, building materials, sports, medical and many other fields, such as body armor, stab-resistant clothing, bulletproof money transport vehicles, shields, armored protective panels for tanks and ships , Parachute cables, marine engineering cables, climbing ropes, fishing nets, fishing lines, rowing boats, sailing boats, bowstrings, tennis rackets, skis, artificial joints and ligaments, safety shields, shock-resistant containers, etc.

1. National defense military equipment
Because the fiber has good impact resistance and greater energy absorption, it can be made into protective clothing, helmets, and bulletproof materials in the military, such as armored shields for helicopters, tanks and ships, protective shells for radars, and missile covers. , Bulletproof vests, stab-resistant vests, shields, etc., among which the application of bulletproof vests is eye-catching. It has the advantage of being light and soft, and its bulletproof effect is better than that of aramid. It has become the main fiber occupying the American bulletproof vest market. In addition, the specific impact load value U/p of the molecular weight polyethylene fiber composite is 10 times that of steel, and more than twice that of glass fiber and aramid. Bulletproof and riot helmets made of fiber-reinforced resin composite materials abroad have become substitutes for steel helmets and aramid-reinforced composite helmets.

2. Aerospace applications. In aerospace engineering, due to the light weight, high strength and good impact resistance of the fiber composite material, it is suitable for various aircraft wingtip structures, spacecraft structures and buoy aircraft. The fiber can also be used as a decelerating parachute for the landing of a space shuttle and a rope for suspending heavy objects on the aircraft, replacing the traditional steel cable and synthetic fiber rope, and its development speed is abnormal.

3. Civilian

(1) Application of ropes and cables: ropes, cables, sails and fishing gear made of this fiber are suitable for marine engineering and are the initial use of the fiber. It is generally used for negative force ropes, heavy-duty ropes, salvage ropes, towing ropes, sailing ropes and fishing lines. The rope made of this fiber has a breaking length under its own weight that is 8 times that of steel rope and 2 times that of aramid fiber. The rope is used for fixed anchor ropes of oil tankers, marine operating platforms, lighthouses, etc., and solves the problems of corrosion, hydrolysis, and ultraviolet degradation of nylon and polyester ropes caused by the corrosion, hydrolysis, and ultraviolet degradation of nylon and polyester ropes. Problems that need to be replaced frequently.

(2) Sports equipment products: Hats, snowboards, windsurf boards, fishing rods, rackets, bicycles, hang gliders, and aircraft parts have been made into sports products, and their performance is better than traditional materials.

(3) Used as a biological material: The fiber-reinforced composite material is used in dental tray materials, medical implants and plastic sutures. It has good biocompatibility and durability, and has high stability. Causes allergies and has been used. It is also used in medical gloves and other medical measures. (4) In industry, the fiber and its composite material can be used as pressure container, conveyor belt, filter material, automobile buffer board, etc.; in construction, it can be used as wall, partition structure, etc., and it can be used as reinforced cement composite material. Improve the toughness of cement and its impact resistance. Uses: bulletproof vests and helmets, lightweight armor, sails, cables, optical cables, parachutes and filters, etc.
