Aramid fiber, known as “aromatic polyamide fiber” in full, is a new high-tech Synthetic fiber, which has excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, light weight, etc. Its strength is 5-6 times that of steel wire, modulus is 2-3 times that of steel wire or glass fiber, toughness is twice that of steel wire, and its weight is only about 1/5 of that of steel wire. At 560 ℃, it does not decompose or melt. It has good insulation and anti-aging performance, and has a long life cycle.
In addition to special applications, aramid fiber has been widely used as a high-tech fiber material in various aspects of the national economy such as aerospace, electromechanical, construction, automobiles, and sports goods. Aramid fiber is suitable for bulletproof vests, helmets, aerospace materials, sports materials, tire frame materials, conveyor belt materials, etc. It has the properties of insulation, high temperature resistance and aging resistance.
