Aramid filament sewing thread has excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. The continuous use temperature range of aramid filament sewing thread is extremely wide, ranging from -196 ℃ to 204 ℃. It can be used for a long time and has good insulation and corrosion resistance, with a long life cycle.
Aramid filament sewing thread has excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. Its specific strength is 5-6 times that of high-quality steel, modulus is 2-3 times that of steel or glass fiber, toughness is twice that of steel, and weight is only 1/5 of steel. The continuous use temperature range of aramid filament sewing thread is extremely wide, and it can be used for a long time within the range of -196 ℃ to 204 ℃. It also has good insulation and corrosion resistance, and a long life cycle.
