1. A synthetic polymer containing imide groups in its backbone, known for high thermal stability, mechanical strength, and chemical resistance.
Usage: technical; chemistry; materials science

Examples

• Polyimide films are widely used in aerospace applications because of their exceptional heat resistance.
• The circuit board was coated with polyimide to protect it from moisture and thermal stress.
• Engineers chose polyimide for the spacecraft insulation due to its durability in extreme temperatures.
• Polyimide adhesives bond metal and composite materials in high-performance aircraft.
• The flexible polyimide membrane allowed the sensor to withstand repeated bending without degradation.
