防彈絲

[產品說明]: 又叫防彈絲或凱芙拉Kevlar，是一種新型高科技合成纖維，具有超高強度、高模量和耐高溫、耐酸耐堿、重量輕等優良性能,其強度是鋼絲的5～6倍，模量為鋼絲或玻璃纖維的2～3倍，韌性是鋼絲的2倍，而重量僅為鋼絲的1/5左右，在560度的溫度下，不分解，不融化。它具有良好的絕緣性和抗老化性能，具有很長的生命周期。芳綸的發現，被認為是材料界一個非常重要的歷史進程。

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.

[應用方式]: 用于高性能電線電纜、光纖光纜、海纜等

Application: Used in high-performance wire and cable, optical cable and submarine cables etc.
