Product Description
The main products of the company are bidirectional stretch polyimide film (BOPI), the main specifications include 12.5μm, 25μm,50μm. The width is within 1100mm. In addition to the high insulation as well as high and low temperature resistance (-273°C-300°C) of traditional polyimide film (PI film), Our product also have the characteristics of low CTE, high support and high flatness. Products are widely used in LED lighting, flexible circuit board, power batteries, tape and other fields.
