High temperature resistant polyimide super engineering plastics have many excellent properties that other engineering plastics do not have: high temperature resistance, low temperature resistance, corrosion resistance, self-lubrication, low wear, excellent mechanical properties, good dimensional stability, small thermal expansion coefficient, high insulation, low thermal conductivity, no melting, no rust, can replace metals, ceramics, polytetrafluoroethylene and engineering plastics in many cases, and are widely used in petrochemical, mining machinery, precision machinery, automobile industry, microelectronic equipment, medical equipment and other fields, with a good performance-price ratio. Widely used in aviation, aerospace, microelectronics, nano, liquid crystal, separation membrane, laser and other fields.
