Product Description

 

Product Description

Transparent polyimide (PI) film, also known as CPI film, is a high-performance polymer material engineered for advanced electronic and optical applications. Compared with traditional amber PI films, it offers excellent optical clarity while maintaining outstanding thermal stability, electrical insulation, and mechanical strength.

 

This film performs reliably in extreme environments, with continuous temperature resistance up to 300°C and short-term exposure even higher. It also features low dielectric constant, high dimensional stability, and strong chemical resistance, making it ideal for flexible electronics, display technologies, and high-end insulation applications.
