Product  Features

聚醯亞胺薄膜是世界上性能的薄膜類絕緣材料，由均苯四甲酸二酐（PMDA）和二胺基二苯醚（DDE）在強(qiáng)極性溶劑中經(jīng)縮聚並流延成膜再經(jīng)亞胺化而成。該膜具有優(yōu)良的耐高低溫性、電氣絕緣性、粘結(jié)性、耐輻射性、耐介質(zhì)性，能在－269℃～400℃的溫度範(fàn)圍內(nèi)長(zhǎng)期使用，短時(shí)可達(dá)到400℃的高溫。

polyimide firm is the best thun-film type insulating material in nowadays world, using the polymerization of PMDA and DDE in strongly polar solvent, followed by cast film formation and imidization., which has a good property of resistance to heat, electrical insulation, adhesion, radioactive and chemical. It can be used in a long term during the temperature between -269℃. to 260℃.. it can also be used under 400℃. in a short term.
