HSQY Capacitor Biaxially Oriented Polyester Film

Capacitor Biaxially Oriented Polyester Film

HSQY capacitor biaxially oriented polyester film, also known as capacitor BOPET film or capacitor-grade PET film, is designed for electronic insulation, capacitor winding, electrical components and industrial film applications that require high tensile strength, stable thickness, excellent dielectric performance and reliable dimensional stability.

BOPET film is produced through a biaxial orientation process that improves mechanical strength, heat resistance, clarity and uniformity. HSQY supplies polyester PET film in different thicknesses, widths, colors and surface treatments for capacitor, packaging, printing, electronics and industrial applications.

Key Advantages of Capacitor BOPET Film

Excellent dielectric performance: Capacitor-grade BOPET film is suitable for electrical insulation and capacitor winding applications that require stable film performance and reliable insulation properties.

High mechanical strength: The biaxial orientation process gives polyester film strong tensile strength, puncture resistance and durability for demanding converting and electronic applications.

Stable thickness and dimension: BOPET film provides good dimensional stability, helping improve winding, laminating, printing and coating consistency.

Heat and chemical resistance: Polyester PET film performs well under changing temperature conditions and resists moisture, oils and many common chemicals.

Custom surface options: HSQY can supply print-treated, slip-treated, hardcoat and untreated film options according to the buyer's converting, printing, coating or insulation requirements.

Clear and glossy appearance: BOPET film provides high clarity and gloss for packaging, labels, box windows and display-related applications.

Applications of Capacitor BOPET Film

Capacitor film: Used for capacitor winding and electrical insulation where stable thickness, dielectric performance and dimensional stability are required.

Electronics: Suitable for insulation films, cable insulation, printed circuit board protection, touch screen panels and display protection.

Packaging and printing: Used for box windows, labels, printed packaging, flexible packaging, laminates and lidding film structures.

Industrial films: Suitable for release liners, thermal transfer ribbons, graphic overlays, moisture barrier structures and composite laminates.
