1. Plural of polyimide; synthetic polymers containing imide groups in their backbone, known for high thermal stability, mechanical strength, and chemical resistance.
Usage: technical; chemistry; materials science

Examples

• Polyimides are widely used in aerospace applications due to their exceptional heat resistance.
• The engineer selected polyimides for the spacecraft components because they maintain strength at high temperatures.
• Polyimides are commonly found in flexible printed circuits and high-performance insulation materials.
• These polyimides can withstand temperatures exceeding 300 degrees Celsius without degrading.
• The chemical resistance of polyimides makes them ideal for use in harsh industrial environments.
