Compared with other synthetic fibers, including nylon, polyester and aramid fiber, UHMWPE fiber has the highest strength-weight ratio. Its strength is 10 times that of the same weight of steel. When the fishing line made of UHMWPE fiber falls into the water, it will float on the water as its smaller density than water.

UHMWPE fiber can be braided into fishing lines, which would be high strength and modulus, abrasion resistance, anti-aging and UV-resistance, and resistance to sea water.
