Biaxially Oriented Polyimide Film

Biaxially Oriented Polyimide Film

Biaxially oriented polyimide film (BOPI) delivers enhanced mechanical strength, thermal stability, and dielectric performance. Ideal for high-end flexible circuits, aerospace insulation, and advanced electronic applications requiring uniform properties.

Biaxially Oriented Polyimide (BOPI) Film is a high-performance film manufactured through a specialized biaxial stretching process, which significantly enhances its properties in both machine and transverse directions.
The stretching process creates a film with more excellent and balanced mechanical strength, dimensional stability, and heat resistance compared to standard films.
Capable of reliable operation across an ultra-wide temperature range, from -269°C to over 400°C.
It is Top-Tier Electrical Insulation,maintains exceptional dielectric properties and insulation integrity even under severe thermal cycling.
