Ultra-high molecular weight polyethylene fiber, is ranked the carbon fibers, boron fibers, aramid fibers for fiber strength after the fourth. With high strength, high modulus, chemical resistance, light resistance, but also humidity, impact resistance, anti-cutting, it's a good biocompatibility and high strength and high modulus fibers in all the density of the smallest, so light and tough.
Russian Academy of Sciences and synthetic fiber pilot plant other companies to cooperate with Russia, completed the first of Russian ultra-high molecular weight polyethylene fiber all the production process, from synthetic fibers, catalysts, to the Preparation of high strength and high modulus yarn and composite materials, this is the first Russian ultra-high molecular polyethylene research, the use of gel spinning super-stretching method, annual output 25 tons.
Of Russian ultra-high molecular weight polyethylene fiber in which two models - ЛЭ-1 type and ЛЭ-2 type, mainly for the manufacture of soft-bullet, bulletproof helmets, bullet-proof armor, super ropes, parachute rope and aerospace composite materials to enhance and so on. ЛЭ-1-type silk into fabrics for reinforced composite materials, the main performance indicators over the Russian production of aramid fabric reinforced composite materials PycaP, the bending stress fracture increased 35%, ЛЭ-2 type is expected to increase more .
Of Russian ultra-high molecular weight polyethylene fiber for industrial production has taken shape in 2011, authorities plan to complete in 2015, commercial operations, and annual production capacity of 120 tons scale. Two types of wire, prices are lower than of Russian aramid PycaP, than the Russian production of polyacrylonitrile-based carbon fiber lower the price of 1 / 3 to 1 / 4.
