Introduction
| Polyimide, also known as PI, has been mass-produced since 1955. | |
| - | It is a thermoplastic or thermoset polycondensate. |
| - | Applications: PI is commonly used in bearing materials, thrust washers, and semiconductor wafer clamps. |
| - | General properties: It has high impact and dielectric strength, high heat resistance (260 ºC continuous, up to 480 ºC intermittent), and a low coefficient of thermal expansion. |
| - | Trade Name: Vespel, Kapton. |
