UHMWPE is high-tech fiber in the first 1990's; Regarded as one of the world's three high performance fibers(carbon fiber,aramid fiber and PE fiber); Possesses such characteristics as low density of 0.97g/cm³,high molecular weight,high degree of orientation and high crystallization;   High molecular weight, high strength. Its tenacity is 15 times over steel and 10 times over normal chemical fiber; the yarns are widely used to make the ropes, cut-resistance gloves, industrial textile fabric, fishing line and fishing nets, bulletproof vest and helmet
