众所周知，汽车制造中涉及很多的材料，特别是为了提高汽车的性能，减轻车身重量，增加外表的美观，国外对汽车使用的材料进行了很多的研究，寻找出经济实用的非金属结构材料。如以粘接剂代替焊接，用玻璃钢板代替金属材料，用电泳漆、粉末涂料取代传统的漆料，因而使环氧树脂在汽车制造工业中的应用越来越广。

随着车中装备的不断完善，如许多汽车上都不同程度地配上录音机、放像机、电视机、监视器、冷气机等，车用绝缘材料的量也随之增加，而这些制品绝缘材料大部分为环氧树脂组成。据国外资料介绍，每辆车约用lang=EN-US>5style=”FONT-FAMILY: 宋体; mso-ascii-font-family: ‘Times New Roman’; mso-hansi-font-family: ‘Times New Roman'”>公斤环氧树脂制品，则我国汽车制造工业中每年需用环氧树脂制品达lang=EN-US>5style=”FONT-FAMILY: 宋体; mso-ascii-font-family: ‘Times New Roman’; mso-hansi-font-family: ‘Times New Roman'”>千吨左右，这是一个相当可观的数字，因此国产环氧树脂如何挤身于汽车制造工业这个大市场，已成为引人注目的事。
