High Tenacity and High Modulus PE Fiber, also called as UHMWPE fiber, is high-tech fiber in 1990's. Regarded as one of the world's three high performance fibers (carbon fiber, aramid fiber and PE fiber), UHMWPE fiber possesses such characteristics as high molecular weight, high degree of orientation and high crystallization. And its tenacity is 15 times over steel and 10 times over normal chemical fiber. Besides its also low density, high modulus, UV resistance, corrosion resistance, outstands anti-impact and anti-incision. UHMWPE fiber is widely used in national defense equipment such as tank, armored car, bulletproof plate, bulletproof helmet, bulletproof jacket, cut-resistance jacket, cut-resistant gloves and fabric; And also used in composites field such as composites materials for aviation and spaceflight, ropes for navy vessel, trawling net, ocean cage against winds and waves, sports equipment and construction projects. In the 1990s, only Holland, USA and Japan can produce such fiber and the fiber was blocked technically by western countries and was forbidden for socialist countries.
