Aramid webbing is woven from Aramid 1414 fiber. It is a new type of composite high-performance webbing. It has extremely high strength (more than 28g/d), 5-6 times of high-quality steel, 2-3 times of modulus of steel or glass fiber, twice of toughness of steel, and 1/5 of weight of steel. The continuous use temperature range of aramid fiber is extremely wide, ranging from - 196. It can operate normally for a long time from C to 204 ℃. The shrinkage rate is 0 at 150 ℃, it does not decompose and melt at 560 ℃, and has good insulation and corrosion resistance, with a long life cycle.
