PI Heating Film Material – Thermosetting & Hot-Press Grade for FPC Flexible Heater Lamination

Our polyimide (PI) flexible heating film is a high-performance thermosetting composite material engineered specifically for custom heater manufacturing, designed to serve as a reliable lamination and insulation layer in FPC flexible heater assemblies. Featuring a multi-layer construction of polyimide film, thermosetting adhesive, and protective release film, it delivers ultra-thin thickness, exceptional flexibility, and strong high-temperature bonding performance. Widely used in battery thermal management, automotive sensor heating, medical diagnostic equipment, and aerospace de-icing systems, our PI hot-press film ensures consistent thermal transfer, excellent dielectric strength, and durable adhesion, making it an ideal choice for demanding flexible circuit heating applications.

• Excellent High-Temperature Resistance & Thermal Stability – Offers outstanding heat resistance, dimensional stability, and electrical insulation, making it ideal for demanding high-temperature applications in FPC heater systems.
• Ultra-Thin & Flexible Structure – The thin-film construction provides superior flexibility and allows seamless integration into compact or curved devices where traditional rigid heaters are not feasible.
• Strong Adhesion After Lamination – The built-in thermosetting adhesive layer ensures robust bonding strength after hot-press lamination, guaranteeing reliable and durable attachment between the PI film and heating circuit components.
• Customizable Dimensions & Layup – Thickness of both PI film and adhesive layer, as well as width and roll length, can be tailored to meet specific customer requirements for diverse applications.
• Process-Ready for Mass Production – Supplied in roll format, our film supports die-cutting, continuous lamination, and automated processing, significantly improving manufacturing efficiency and reducing production costs.
