CPI

CPI (colorless polyimide, Colorless PolyiMide) has the characteristics of foldability, flex resistance, high heat resistance, high reliability, low density, etc., is the key substrate and protective layer material of flexible touch folding screen, and can also be used for thin-film solar cells, substrates of flexible circuit boards, etc.

 

History of transparent electrodes

 

 

HKT Global's original CPI

The CPI film based on CPI-ink + SNW Coating process pioneered by Huake Chuangzhi is extremely advanced in terms of ultra-thinness, optics, and folding resistance indicators.
