Polyimide Composite Film Description:

Polyimide Composite Film is a high-performance insulating material available in two main types: high-temperature adhesive film (FH/FHF), which is coated with F46 (polyperfluoroethylene propylene emulsion) and processed at 350°C, and low-temperature adhesive film, which is coated with modified polyester-imide and processed at 250°C. Both types exhibit excellent thermal resistance, electrical insulation, radiation resistance, and high-temperature self-sealing properties, making them ideal for use as insulation layers in wires, cables, and electromagnetic wires. These films maintain stability in extreme environments, ensuring reliability in demanding industrial applications.
