POLYIMIDE
FILM
HIGH-TEMPERATURE ELECTRICAL INSULATION
Polyimide Film for High-Temperature Electrical Insulation
High-performance polyimide film for electrical insulation applications requiring thermal stability, dielectric insulation and dimensional reliability in demanding operating environments.
Product Overview
Polyimide film is used in electrical and electronic insulation systems where conventional films may not provide the required combination of heat resistance, electrical insulation and mechanical durability.
3A Associates can support polyimide film requirements for motors, generators, transformers, coils, flexible electrical assemblies and other high-temperature insulation applications.
The appropriate film grade and thickness should be selected according to operating temperature, voltage, dielectric requirement, mechanical stress and the overall insulation system.
Key Features
1. High-Temperature Insulation
Suitable for insulation systems exposed to elevated operating temperatures, depending on the selected grade.
2. Electrical Insulation Performance
Provides a thin-film electrical insulation layer for demanding components and assemblies.
3. Dimensional Stability
Supports applications where stable insulation performance is required under heat and mechanical stress.
4. Flexible Film Format
Can be used in wrapped, layered, slot, barrier and fabricated insulation constructions.

Polyimide Film Selection Guide
Film selection should be based on the complete electrical and thermal requirement of the insulation system rather than thickness alone.
Electrical Requirement
Consider voltage, dielectric separation and the position of the film within the insulation system.
Thermal Environment
Match the grade to continuous and peak temperature exposure in the finished application.
Mechanical & Processing Needs
Consider flexibility, forming, wrapping, cutting, lamination and compatibility with the surrounding insulation materials.
