UHMWPE Polyethylene fiber

Ultra high molecular weight polyethylene fiber (UHMWPE chopped fibers) is the third generation of high-performance fibers, following carbon fibers and aramid fibers. It is currently the fiber with the highest specific strength and bulletproof performance among industrialized fiber materials. It has excellent properties such as ultra-high strength, ultra-high modulus, low density, wear resistance, low temperature resistance, UV resistance, shielding resistance, good flexibility, high impact energy absorption, and resistance to strong acids, alkalis, chemical corrosion, etc, It is widely used in military equipment, marine industry, safety protection, sports equipment and other fields. In the field of construction, ultra-high strength polyethylene fibers have several times the strength of ordinary polypropylene fibers and polyethylene fibers. They can be used in other high-performance concrete such as ECC and UHPC, as well as in the production of lightweight and high-strength building materials and concrete components, to improve the strength and durability of concrete.

Performance characteristics
 
1. High specific strength and high specific modulus. The specific strength is more than ten times that of steel wire with the same cross-section, and the specific modulus is only second to that of high-grade carbon fiber.
2. The fiber density is low, ranging from 0.97 to 0.98g/cm3, and can float on the water surface.
3. Low elongation, high fracture work, and strong energy absorption ability, thus possessing outstanding impact resistance and cutting resistance.
4. UV radiation resistance, neutron resistance, and γ X-rays have high specific energy absorption, low dielectric constant, and high electromagnetic wave transmittance.
5. Chemical corrosion resistance, wear resistance, and long bending life.
