AT High Temperature Insulation Polyimide Film

Description

AT High Temperature Insulation Polyimide Film is a high-performance polyimide film designed for electrical insulation, thermal protection, and demanding electronic applications. It offers excellent dielectric strength, dimensional stability, chemical resistance, radiation resistance, and flame resistance. With a wide operating temperature range from -269°C to 400°C, this film is suitable for wire and cable insulation, motor slot liners, transformer insulation, capacitor insulation, F-PCB coverlay, stiffeners, polyimide labels, and tubing applications. Its stable mechanical and electrical properties make it a reliable material for high-temperature insulation systems.

Key Features

• High Dielectric Strength: Provides excellent electrical insulation performance, making it suitable for motors, transformers, capacitors, wires, cables, and electronic insulation structures.
• Outstanding Thermal Stability: Performs across a wide temperature range from -269°C to 400°C, supporting use in both extreme low-temperature and high-temperature environments.
• Dimensional and Mechanical Stability: Maintains reliable tensile strength, elongation, and low shrinkage under heat exposure, helping reduce deformation in precision insulation applications.
• Chemical, Radiation and Flame Resistance: Offers strong resistance to chemicals, radiation, and flame, with UL V-0 flame resistance and UL-qualified film options available.

Applications

• Wire, Cable and Motor Insulation: Used for wire and cable tapes, motor slot liners, magnet wire insulation, and formed coil insulation.
• Transformer and Capacitor Insulation: Provides reliable insulation layers for transformers, capacitors, and other high-performance electrical components.
• F-PCB and Electronic Materials: Suitable as coverlay or stiffener material in flexible printed circuit boards, as well as polyimide adhesive tape or laminate base film.
• Labels, Tubing and Specialty Processing: Used for high-temperature polyimide labels, polyimide tubing, and custom insulation parts requiring dimensional stability and heat resistance.
