| High Light | Electrical Grade Capacitor PET Film ，High Dielectric Strength BOPET ，Ultra-Thin Insulation Polyester Film | ||
This ultra-thin electrical grade BOPET film is a precision-engineered biaxially oriented polyester film designed for demanding electrical insulation and capacitor applications. With dielectric strength exceeding 300 kV/mm and ultra-thin gauges from 2 to 12 μm, the film is the industry choice for metallized film capacitors, motor slot liners and transformer interlayer insulation.
The low dissipation factor of ≤0.005 at 1 kHz minimizes energy loss and heat generation in AC and pulse applications, while Class B (130°C) and Class F (155°C) thermal ratings ensure reliable long-term operation. A smooth surface finish of Ra ≤0.04 μm enables uniform metallization and consistent capacitance, and the film carries UL 94 VTM-0, RoHS and REACH compliance for worldwide electronic component market access.
