This advanced transparent polyimide film eliminates the traditional compromise between optical clarity and high-temperature performance. Its unique combination of properties enables optoelectronic designers to push the boundaries of what's possible in high-temperature optical applications while maintaining excellent mechanical flexibility and long-term reliability. The material's stability under extreme conditions makes it particularly valuable for applications where conventional transparent polymers would rapidly degrade or lose optical performance.
To ensure the longevity and performance of our Polyimide film,
please adhere to the following guidelines:
· Store in a cool, dry place away from direct sunlight will be
necessary.
· Avoid exposure to high humidity or extreme temperature
fluctuations.
