FLUORINATEDPOLYIMIDE RESIN
Fluorinated polyimides are polymers which introduce fluorinated groups into polyimides. In addition to high temperature resistance, environment stability, electrical insulation and good mechanical properties etc, they also have excellent gas separation performance. In addition,the introduction of fluorine-containg groups greatly improve the solubility of flourinated polyimides, thus improving the processabilty of the products.
