昨日博客中提到LCP材料的粘接问题，今日收集了一些LCP液晶高分子聚合物（Liquid Crystal Polymer）相关知识和资料和大家分享，一下均摘自网络，欲了解更多的相关知识可以下载附件几篇文章学习之：

液晶高分子聚合物

液晶高分子聚合物（Liquid Crystal Polymer），简称LCP。是80年代初期发展起来的一种新型高性能工程塑料　　

一、概述

LCP是一类具有杰出性能的新型聚合物。LCP是包含范围很宽的一类材料：

G-930 Titan®

相对密度 1.60 1.63 1.66 1.67 1.61 1.62

二、LCP的特性与应用

1、特性

2、应用

LCP已经用于微波炉容器，可以耐高低温。LCP还可以做印刷电路板、人造卫星电子部件、喷气发动机零件：用于电子电气和汽车机械零件或部件；还可以用于医疗方面。

三、LCP的注塑工艺

由于改性后的性能和用途级别相差很大，其加工工艺变数也很大，故应相应调整如下范围：

四、主要生产公司

①Du Pont、

五、其它了解

热致性LCP具有全芳香族聚酯和共聚酯结构。它还具有密集排列的直链聚合物链结构，形成的产品具有良好的单向机械性能特点。良好高温性能（热变形温度为121～355℃）、良好的抗辐射性、抗水解性、耐候性、耐化学药品性、固有的阻燃性、低发烟性、高尺寸稳定性、低吸湿性、极低的线膨胀系数、高冲击强度和刚性（按相同重量比较，LCP的强度大于钢，但刚性只是钢的15%）。LCP可以耐酸、溶剂和烃类等化学品，并有较好的阻隔性。

找到这款产品是因为有个客户咨询到LCP材料的粘接，我在网上找了半天，后来发现hysol这款产品是专门针对LCP及有机硅粘接的型号，不过此胶水资料显示的是环氧体系的。 关于LCP材料，网上的内容也不是太多，简单理解成为液晶聚合物，关于LCP网上搜集了一些资料，会在另一篇博客中再详述，先将此份资料摘录如下，有兴趣的朋友可以下载附件查看之：
