Ultra high molecular weight polyethylene fiber (UHMWPE), also known as high strength PE fiber, is one of the three high-tech fibers (carbon fiber, aramid fiber and ultra high molecular weight polyethylene fiber) in the world, and also the toughest fiber in the world. Its strength is more than 10 times that of high-quality steel. Its high modulus is second only to super carbon fiber. Its density is less than 1. It can float on the water. It has excellent physical and chemical properties. It is water-resistant, abrasion resistant, UV resistant and chemical corrosion resistant. It is widely used in defense equipment, aviation, protective equipment, marine fishery, cable, sports goods, medical equipment,construction and etc..
