The most prominent properties of the Para Aramid are its high strength, high modulus and heat resistance. For Para Aramid, ratio of weight/strength is 6 times of steel wire, 3 times of glass fiber and twice of high-strength nylon. Ratio of weight / modulus is 3 times of steel wire, twice of glass fiber and 10 times of high strength nylon. Para Aramid can keep 95% strength after working for 500 hours at 160°C and keeps 75% strength after working for 100 hours at 200°C. Para Aramid is often used as a special structure material with properties of light weight, heat-resistant.
