玻纖增強尼龍改性塑料在汽車領域的應用

PA兼具(ju)優良的熱學能、電能、耐腐、耐催(cui)化醫藥性、滑潤性，但也(ye)會存在較出色的劣勢，如吸濕性最(zui)大，促使澆(jiao)注大小(xiao)穩界(jie)定高(gao)性差。以至于(yu)，要想(xiang)把PA看(kan)作施工(gong)型式(shi)材質，還(huan)需改善其(qi)能，功能高(gao)達工(gong)業(ye)品(pin)貸(dai)款用途的標(biao)準要求。為之，霖源滲(shen)透型滌綸廠商為大家整理了玻璃纖維增強尼龍的改性方法，一起來看看吧！玻纖增強是一種常用的改性手法。可以有效增強尼龍的耐磨性、強度、硬度、尺寸穩定性。
