聚酰亚胺薄膜是由均苯四甲酸二酐(PMDA)和二胺基二苯醚(DDE)在强极性溶剂中
经缩聚并流延成膜再经亚胺化而成。聚酰亚胺薄膜具有优良的耐高低温性、电气
绝缘性、粘结性、耐辐射性、耐介质性,能在-269℃~260℃的温度范围内长期
使用,是目前乃至很长的一段时期内性能最好的一种合成材料。被称为"黄金薄膜
"的聚酰亚胺薄膜具有卓越的性能。
应用领域:它广泛的应用于空间技术、F、H级电机、变压器等电器的绝缘、FPC
(柔性印刷线路板)、TAB(压敏胶带基才)、航天、航空、计算机、电子元器件工业、汽车、交通运输、原子能工业直至高档的家用电器等,是现代化工业比不可缺的材料。
Polyimide film is made up of both pyro mellitic di-anhydride(PMDA) and 2 amino diphenyl ether (DDE)? approved by polycondensation and stretch film again the imminent strong polar solvent?.Polyimide film has
excellent high and low temperature resistance, electrical insulation resistance,caking property, radiation resistance and medium resistance.Use for a long time in the temperature range of -269 ~ 260?.Its one of
the best synthetic material at present and even for a long time. It was called “golden film” and have
excellent performance.
Application: ts was widely used in space technology, F and H motor, the insulation of the electric equipment such as transformers, FPC (flexible printed circuit board), TAB (pressure sensitive adhesive tape only), spaceflight, aviation, computer, the electronic components industry,automobile, transportation,atomic energy industry and high-grade household electrical appliance set. Its the indispensable materials in modern industry.
