AT Aluminum Polyimide Film

Description

AT Aluminum Polyimide Film is a high-performance functional film made by sputtering a thin aluminum layer onto polyimide film. One side provides excellent electrical insulation, while the aluminum-coated side offers high conductivity, EMI shielding, and thermal conductivity. This film combines the heat resistance, mechanical strength, chemical stability, radiation resistance, and self-extinguishing properties of polyimide with the shielding performance of metal coating. It is suitable for aerospace, electronics, electromagnetic shielding, flexible circuits, and applications requiring insulation, conductivity, and high-temperature stability.

Key Features

• Effective EMI Shielding: The aluminum-coated surface provides conductive shielding performance, helping reduce electromagnetic interference in electronic and aerospace applications.
• Dual-Side Functional Structure: One side retains the insulation properties of polyimide film, while the aluminum side offers high conductivity and thermal transfer performance.
• High Temperature and Radiation Resistance: Polyimide backing maintains stable mechanical and electrical properties under heat, radiation, and demanding operating environments.
• Halogen-Free and Flame-Retardant: Environment-friendly film structure with self-extinguishing performance helps improve safety in sensitive electronic and industrial applications.

Applications

• • Aerospace and Space Protection: Used for radiation-resistant inner layers of space suits, aerospace shielding structures, and high-performance protective films.
  • EMI and Electromagnetic Shielding: Suitable for EMI shielding layers, electromagnetic shielding tapes, and electronic devices requiring conductive protection.
  • Sealing and Functional Film Applications: Can be used as sealing material where heat resistance, dimensional stability, and conductive performance are required.
  • Flexible Electronics and Etching Wires: Suitable for flexible etching wires, flexible circuit structures, and applications requiring both insulation and conductive surface performance.
