UHMWPE fiber, also known as high-strength and high modulus polyethylene fiber, has the characteristics of high strength, high modulus, corrosion resistance and low density. It is the fiber with high specific strength and specific modulus in the world at present, and it is the fiber spun by polyethylene with molecular weight of 1-5 million.

UHMWPE fiber has good mechanical properties, high modulus, high energy absorption and impact resistance. It has better wear resistance than other high-performance fibers. The fiber has corrosion resistance, the strength will not be reduced in acid and alkali solution, it will not swell and hydrolyze in seawater, and it has the ability to resist ultraviolet, sunlight and mildew.

As one of the high-performance fibers, UHMWPE fiber is widely used in bulletproof, rope and cable, sporting goods, cage and other fields. With the increasing demand and technological progress, UHMWPE fiber will have more extensive development space in the production process, product modification and expansion.
