环氧树脂薄膜电容具有优良的阻燃性，是在原始薄膜电容的基础之上进行了更高技术要求的升级。之所以采用环氧树脂是因为环氧树脂及其固化物是热固性树脂中综合性能最好的。

　　Epoxy resin film capacitor has excellent flame retardancy, which is an upgrade of higher technical requirements based on the original film capacitor. The reason why epoxy resin is used is that epoxy resin and its cured products are the best comprehensive performance among thermosetting resins.

　　环氧树脂是泛指分子中含有两个或两个以上环氧基团的有机高分子化合物，活泼的环氧基团可以位于分子链的末端、中间或成环状结构。环氧树脂薄膜电容具备了环氧树脂的所有优点。

　　Epoxy resin is a kind of organic polymer with two or more epoxy groups in the molecule. The active epoxy group can be located at the end, middle or ring structure of the molecular chain. Epoxy resin film capacitor has all the advantages of epoxy resin.

　　1、它有优良的物理机械性能、电绝缘性，固化收缩率小；

　　It has excellent physical and mechanical properties, electrical insulation and small curing shrinkage;

　　2、稳定性好，固化后的环氧树脂主链是醚键和苯环，三维交联结构致密又封闭，因此它耐酸、耐碱及多种介质；

　　The cured epoxy resin has good stability. The main chain of cured epoxy resin is ether bond and benzene ring, and its three-dimensional cross-linking structure is dense and closed, so it is resistant to acid, alkali and various media;

　　3、粘结强度高，尤其是环氧基团能与固化剂作用交联生成大分子，具有很强的内聚力；

　　The adhesive strength is high, especially the epoxy group can react with curing agent to form macromolecules and has strong cohesive force;

　　4、原料容易取得，制造技术并不复杂，设备也比较简单且工艺性好；

　　Raw materials are easy to obtain, the manufacturing technology is not complex, the equipment is relatively simple and the process is good;

　　5、使用方便，能作为涂料，电气绝缘材料，胶粘剂浇注料，灌封料，包封料及玻璃钢等，用途十分广泛，在国民经济各领域中起着不可缺少的重要作用。

　　Easy to use, it can be used as coating, electrical insulation material, adhesive, castable, potting material, wrapping material and glass fiber reinforced plastic, etc. it is widely used and plays an indispensable and important role in various fields of national economy.

　　环氧树脂薄膜电容在电网建设、电气化铁路建设、节能照明、混合动力汽车等市场需求呈现了快速增长的趋势。

　　The demand of epoxy resin film capacitor in power grid construction, electrified railway construction, energy-saving lighting, hybrid electric vehicle and other market demand shows a rapid growth trend.
