590LC DuPont™ Kapton® Tape
Polyimide has several advantages over polyester, making it a preferred choice in certain applications.
usage
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.
