UHMWPE Fiberis made of Ultrahigh Molecular Poyethlene(UHMWPE) passing frozen-glue silk and Ultra-times drawing, the formal inter-binding and disorderly PE molecules are gradually unbinded, and reaches a high level of orientation and crystallization, making fiber light, soft,strong, modulus. Moreover, it has features of anti-UV, anti-lashing, anti-erosion and so on. Basic features of fiber are as follow: *High strength:10times stronger than the high-quality steel of the same section in intension ; *High modulus:next to the super-class carbon fiber; *Low density:0.97, and floatable on water; *Anti-UV; *Anti-erosion--anti-acerbity, anti-alkali, anti-seawater; *Extraordinary anti-abrasive, flexible, anti-bend The melting point of UHMWPE Fiber is between 144 to 152degree. The highter the temperature is, the lower the strength and modulus will be, but there in nearly no changes below 0 degree.There is no brittle point the temperature lower than -150 degree. So this fiber can be applied at the tempererature ranging from -150 to 70 degree and there is no sharp decline of the product's property and if it is exposed in short time on condition of 110 degree environment. Based on UHMWPE Fiber's so advantageous properties, it has now become one of the high-tech material rapidly developed in recent years and wildly applied in such fields as safety protection, aviation, spaceflight, navigation, electronics, weapon, shipbuilding, building material, sports, medical treatment and so on. Products made up of the fiber include bulletproof jacket, bllistic helmet, financial vehicle, ballistic shield, tank, naval armor protection board, parachute hawser, watercraft oceaneering cordage, mountain-climbing rope, fishing net and tread, boat, gig and arrow, pat, ski, man-made nearthrosis and ligament, safety protection cover, anti-impact vessel and so on.
