PI heating film is designed for low-temperature heating applications where flexibility, light weight, and efficient surface heating are important. Built with polyimide film and a copper foil heating circuit, it offers a compact heating structure that is easy to integrate into battery systems and other space-limited assemblies.
For battery applications, the film can be attached to the side of a battery PACK or wrapped around cells to provide conductive heating. This helps improve low-temperature startup performance, maintain better thermal consistency, and support more stable system operation in cold environments.
