high modulus (2 ~ 3 times of steel wire) and low specific gravity(1/5 of steel wire) . Used for high-speed aircraft tire cord,deep-sea operations, aerospace, such as special cable. The latteris characterized by high temperature resistance, flame in theflame, with self-extinguishing, aging resistance, but poorresistance to ultraviolet. For inflammable and explosiveenvironment of the work clothes and spacesuit, fire-fightingclothing.
