Low-Loss Capacitor Film Delivering Stable Dielectric Performance

NanoPlex LDF is a capacitor film designed to outperform conventional BOPP. With a low dissipation factor and stable dielectric behavior up to 135°C, it’s engineered for high-frequency, high-temperature applications like fusion energy systems, EVs, renewables, HVDC, grid, and pulsed-power defense platforms.

Easily metallized and wound using existing infrastructure, LDF eliminates the need for major retooling. By extending operational lifetime and thermal reliability, it slashes maintenance costs and enables more compact, efficient system designs.

Frequently Asked Questions: NanoPlex™ LDF Film

NanoPlex LDF offers a higher operational temperature range - up to 135°C - compared to BOPP’s ~85°C limit. It delivers a similar low dissipation factor (extended to 150°C) while enabling longer device lifetimes, smaller form factors, and more reliable high-temperature performance.

Yes. LDF is engineered for compatibility with existing BOPP processing tools. It handles like standard BOPP film, minimizing retooling or requalification requirements for capacitor manufacturers.

Higher thermal stability means capacitors can operate without derating in elevated temperature environments. This results in fewer components, reduced cooling needs, and longer operational life. This is critical for fusion energy, defense systems, and grid modernization.

Samples are now available throughout 2025–2026, with large-volume production planned for 2027 at Peak Nano’s U.S.-based manufacturing facility.

More than 70% of BOPP film is sourced from overseas, often with uncertain lead times and geopolitical risk. Peak Nano’s U.S.-based production provides a secure, compliant, and resilient supply chain for critical industries.
