Why Universal Metals

Versatile Electrical Insulation Film

Biaxial Orientation
Simultaneous stretching in machine and transverse directions creates uniform molecular alignment, resulting in balanced mechanical properties and exceptional dimensional stability across all axes.
High Dielectric Strength
Breakdown voltage exceeding 200V/μm makes BoPET ideal for capacitor dielectrics and high-voltage cable insulation applications requiring consistent electrical performance.
Dimensional Stability
Minimal thermal shrinkage (typically <0.3% at 150°C for 30 min) ensures reliable performance in motor slot liners, transformer insulation, and capacitor dielectric applications.
