Cirlex® CL Polyimide Film

Cirlex® CL Polyimide Film provides stable electrical insulation and mechanical support in high-heat, vacuum, and radiation-exposed environments for industrial, laboratory and research applications. It is used in semiconductor fabrication for wafer carrier components, in aerospace systems for thermal and electrical insulation, and in high-energy detectors as a structural layer. Its low outgassing and dimensional stability make it suitable for cleanroom and vacuum applications. Cirlex®’s resistance to chemicals and thermal cycling ensures long-term reliability in precise R&D assemblies and instrumentation. It is also used in cryogenic cabling, superconducting qubit packaging, radiation detectors, and deep-UV lithography setups where low dielectric loss and thermal endurance are critical.
