Thermosetting polyimides are known for thermal stability, good chemical resistance, excellent mechanical properties, and characteristic orange/yellow color. Polyimides compounded with graphite or glass fiber reinforcements have flexural strengths of up to 340 MPa (49,000 psi) and flexural moduli of 21,000 MPa (3,000,000 psi). Thermoset polymer matrix polyimides exhibit very low creep and high tensile strength. These properties are maintained during continuous use to t… WebIn the following sections, a conductive, piezoresistive graphite-filled polyimide which is compatible with conventional microelectronics processing techniques is discussed. Conductive composite polyimide films have been studied extensively for use in a variety of applications including die attach, thermistors, electromagnetic shielding, anti ...
