Mylar® film for electrical and electronic insulation

Industrial Mylar® film is widely used for:

Insulation of electric motors
Transformer intercalaires
Electronic isolation modules
Printed circuit protection
Lithium-ion battery applications
Automotive embedded electronics

Its dielectric strength allows for use in controlled electrical environments, while optimising costs compared to higher-end polyimide solutions.

High-temperature Mylar®: what are the limits?

The Mylar® PET film supports moderate temperatures suitable for the majority of standard industrial applications.

When thermal constraints become extreme (> 250°C), alternatives such as polyimide are recommended.

Our experts will help you determine if the Mylar® polyester film meets your specifications.
