UL-Certified, Dual-Side Corona Treated BOPI Film For Extreme Temperatures

The high-performance, industrial-grade biaxially oriented polyimide (BOPI) film is engineered for the most demanding applications, delivering exceptional thermal stability, outstanding mechanical strength, and reliable electrical insulation.  Through a specialized biaxial orientation process, the film achieves superior dimensional integrity and durability.  Additionally, both surfaces receive precisely controlled corona treatment to promote excellent adhesion for coatings, laminates, and metallized layers.

• Extreme Temperature Stability: Exceptional resistance to both high and low temperatures, supported by a high glass transition temperature (Tg).
• Outstanding Mechanical Properties: High tensile strength, tear resistance, rigidity, and dimensional stability under stress.
• Superior Electrical Insulation: Ideal for use as a reliable dielectric material in demanding electrical applications.
• Excellent Chemical Resistance: Highly resistant to a wide range of organic solvents, oils, greases, and other chemicals.
• Inherent Flame Retardancy: Self-extinguishing properties with compliance to strict flame-retardancy standards;  does not sustain combustion.

Applications:

• Heat-Resistant Heaters & Sensors: Provides a durable, thermally stable dielectric and protective layer in flexible heating elements and sensor arrays.
• High-Temperature Barrier & Release Films: Suitable for demanding processing environments requiring thermal resilience.
• EMI Shielding: Serves as a robust substrate for metallized shielding films that effectively block electromagnetic interference.

This UL-certified, dual-side corona-treated BOPI film offers manufacturers a robust and high-performance material solution, delivering exceptional process compatibility and end-product dependability.
