[产品说明]: 又叫防弹丝或凯芙拉Kevlar，是一种新型高科技合成纤维，具有超高强度、高模量和耐高温、耐酸耐碱、重量轻等优良性能,其强度是钢丝的5～6倍，模量为钢丝或玻璃纤维的2～3倍，韧性是钢丝的2倍，而重量仅为钢丝的1/5左右，在560度的温度下，不分解，不融化。它具有良好的绝缘性和抗老化性能，具有很长的生命周期。芳纶的发现，被认为是材料界一个非常重要的历史进程。
Product Description: Also called bulletproof yarn or Kevlar, is a new high-tech synthetic, has ultra-high strength, high modulus volume, resistance high temperature, acid and alkali resistant, and light weight, such as 5 ~ 6 times that of steel wire on its strength, modulus of steel wire or fiber glass 2 ~ 3 times, toughness is 2 times of wire, and weight is only about 1/5 of the steel wire, under the temperature of 560 ° C, Won't to resolve and melt. It has good insulation properties and anti-aging properties, with a long life cycle. Aramid finds, is considered to be a very important historical material processes.
