Polyimide has several advantages over polyester, making it a preferred choice in certain applications.

Mechanical Strength

Polyimide offers better mechanical strength and dimensional stability, making it more durable and reliable in challenging environments.

Electrical Insulation

Polyimide has superior electrical insulation properties compared to polyester. It maintains its insulating capabilities even at elevated temperatures, which is crucial for electronics and electrical components.

Heat Resistance

Polyimide exhibits exceptional heat resistance, withstanding much higher temperatures than polyester. It can handle temperatures up to several hundred degrees Celsius without degrading, making it suitable for high-temperature applications in electronics and other industries.

Low Outgassing

In vacuum and space applications, polyimide produces lower levels of outgassing compared to polyester, which is essential to avoid contamination in sensitive environments.

Chemical Resistance

Polyimide is more resistant to various chemicals, solvents, and oils than polyester, making it suitable for applications where exposure to these substances is a concern.
