| 150D-3000D Para aramid fiber kevlar filament yarn bullet proof filament | ||||
| Kevlar yarn, also known as aramid yarn, or para aramid yarn, is a new type of high-tech synthetic fiber. It has high strength, high modulus, high temperature resistance, acid and alkali resistance, light weight and other excellent properties. | ||||
| Its strength is 5-6 times that of steel wire, its modulus is 2-3 times that of steel wire or glass fiber, and its toughness is 2 times that of steel wire, while its weight is only 2 times that of steel wire. About one fifth of the steel wire does not decompose or melt at 560 degrees. It has good insulation and aging resistance, and has a long service life. | ||||
