Standard polyimide films (25–125 μm) are suitable for applications such as motor slot liners, transformer insulation, and flexible heater substrates. Ultra thin films (less than 20 μm) focus on flexibility and low stiffness, with common sizes being 5, 7.5, 12.5, and 18 μm. Natural Yellow: The standard form, offering the best balance of properties for most electronic applications. Clear (Transparent): Used in optical touch panels, flexible displays, and applications requiring visual inspection through the film. Black: Provides light blocking for photosensitive devices, camera modules, and display backplanes. https://tianjinfortune.com/products/
