    LCP特性

            

            A:液晶又可分为溶致液晶聚合物和热致液晶聚合物。前者在溶剂中呈液晶态，后者因温度变化而呈液晶态。B:液晶聚合物分子的分之主链刚硬，分子之间堆砌紧密，且在成型过程中高度取向，所以具有线膨胀系数小，成型收缩率低和非常突出的强度和弹性模量以及优良的耐热性，具有较高的负荷变形温度，有些可高达340℃以上。C:LCP的耐气候性、耐辐射性良好，具有优异的阻燃性，能熄灭火焰而不再继续进行燃烧。其燃烧等级达到UL94V-0级水平。LCP塑胶原料是防火安全性最好的特种塑料之一。D:一般热致性液晶聚合物具有较好派的流动性，易加工成型。其成型产品具有液晶聚合物特有的皮芯结构，树脂本身具有纤维性质，在熔融状态下有高度的取向，故可起到纤维增强的效果。这也是液晶聚合物最引人注目的特点。E:热致液晶聚合物还可与多种塑料制成聚合物共混材料，这些共混材料中液晶聚合物起到玻纤增强的作用，可以大大提高材料的强度、刚性及耐热性等。F:LCP塑胶原料密度为1.4~1.7g/cm3。液晶聚合物具有高强度，高模量的力学性能，由于其结构特点而具有自增强性，因而不增强的液晶塑料即可达到甚至超过普通工程塑料用百分之几十玻璃纤维增强后的机械强度及其模量的水平;如果用玻璃纤维、碳纤维等增强，更远远超过其他工程塑料。G:LCP液晶聚合物还具有优良的热稳定性、耐热性及耐化学药品性，对大多数塑料存在的蠕变缺点，液晶材料可忽略不计，而且耐磨、减磨性均优异。H:LCP塑胶原料具有优良的电绝缘性能。其介电强度比一般工程塑料高，耐电弧性良好。作为电器应用制件，在连续使用温度200~300℃时，其电性能不受影响。而间断使用温度可达316℃左右。I:LCP塑胶原料具有突出的耐腐蚀性能，LCP制品在浓度为90%的酸及浓度为50%的碱存在下不会受到侵蚀，对于工业溶剂、燃料油、洗涤剂及热水，接触后不会被溶解，也不会引起应力开裂。
