Hantai aramid knitting sleeve is knitted with aramid 1414, which has high strength, modulus is 2-3 times of steel or glass fiber, toughness is 2 times of steel, and weight is only 1 / 5 of steel. The temperature range of continuous use is - 196. It can operate normally for a long time in the temperature range from 0 ℃ to 204 ℃. The shrinkage at 150 ℃ is 0, and it does not decompose and melt at 560 ℃. It has higher heat resistance, good insulation and corrosion resistance, and long life cycle. The product has the advantages of light weight, high strength, high modulus, stable size, low shrinkage, puncture resistance, wear resistance, heat resistance, chemical corrosion resistance, flame retardancy and good mechanical properties. It is widely used for mechanical protection of glassware, wire harness, cable, etc.
