摘要
轶纶短纤维是国内首个工业化生产的聚酰亚胺纤维,其具有多方面的优良性能:热分解温度>500℃;280℃热空气处理100 h后抗拉伸强度保持率>80%;热导率4.58 W/(K m2),低温保暖性能优越;耐化学酸碱性优于其他同类产品,极限氧指数>38%,阻燃性能好;耐高温过滤性绝佳。因此,轶纶短纤维可于苛刻的高温环境中应用。
Yilun short fiber is the first type of commercially available polyimide fibers manufactured in China.The fiber shows a combination of a variety of excellent properties.The thermal decomposition temperature is above 500 ℃.After aged at 280 ℃ for 100 hours in air,it can maintains 80% of the tensile strength.Its heat transfer coefficient is 4.58 W/（K m2）.It has excellent thermal insulation at low temperature.It showed improved chemical resistance compared to the counterparts in the market.It has good flame retardation with a limit oxygen index of 38.It also has excellent high temperature filtration performance.Therefore,Yilun short fiber can be utilized in the harsh conditions including high temperature,highly corrosive environment,and so on.
