It is understood that polyimide has become the most heat-resistant organic polymer material in the world since its first appearance. So far, polyimide is also one of the organic polymer materials with the best comprehensive performance. It not only has the current market hot transparent side, but also a kind of "gold film", membrane chain today will introduce its other USES in our lives
◤ FPC
FPC, called soft board or flexible circuit board, flexible printed circuit board, etc., is a flexible copper clad board (FCCL) made of a high degree of reliability, excellent flexibility of the printed circuit board. Traditional flexible copperplate substrate is PI, but with the advent of 5G era, PI soft plate has been unable to meet the needs of consumers, now modify PI has come into our sight. Although modify PI is not as good as LCP in terms of transmission loss, dimensional stability and bendability, its efficiency can be improved by improving fluoride formula, and its cost is only 70% of LCP. It has also been revealed that the original LCP software used in the new apple iPhone will be replaced by modify PI.
In addition, PI can also be used as a cover film for FPC. Currently, the 7.5 micron PI cover film used in smart phones is mainly produced by Korean enterprises. But some domestic enterprises have developed excellent performance FPC PI cover film, May 2018 news, FPC manufacturing with the thinest 7.5 muon black PI cover film product, chuzhou detai electronic technology co., ltd. successfully put into mass production. And concerned personage inside course of study says, this product already got domestic relevant FPC manufacturer to evaluate, try, had good evaluation to it.
◤ Diaphragm
It is reported that imide has the world's first polyimide window film, service life than other ordinary window film. In addition, this kind of window membrane is also flame retardant, does not spread combustion carbonization, no open fire will automatically go out, the process of fire will not release toxic and harmful substances. In daily use, the window membrane can block 99% ultraviolet light and the visible light transmittance is more than 85%.
Hunan QiJieXin electronic technology co., LTD. (www.zgqjkj.com/www.qjxdz.com) specialized in manufacturing of electromagnetic heating heat roller, we have successfully break through 500 degrees high temperatures, the saving electricity was above 60%, and roll surface temperature uniformity + / - 1 ℃, the temperature control precision of plus or minus 0.1 ℃. Energy saving and environmental protection, intelligent operation, safe and reliable, thus improving the output and product quality, low maintenance cost, less trouble, long service life.
