Peak Nano Wins Two US Patents for High-Temp Capacitor Films
Valley View, Ohio – October 12, 2026 -- Peak Nano has secured two U.S. patents for dielectric capacitor films that it says deliver four times the energy density of current biaxially oriented polypropylene (BOPP) film and hold full capacity up to 135°C, versus the 85°C limit of industry-standard BOPP.
Patent US12427754B2 targets smaller capacitor banks with a multilayered HDC film
The first patent covers Peak Nano's corona-treated multilayered High Dielectric Constant (HDC) film. Its surface modifications are optimized for metallization, tighter winding and integration in wound metallized capacitors.
The company says the nanolayer architecture delivers four times higher energy density and greater stability than state-of-the-art BOPP. Engineers can design capacitor banks up to two times smaller, cutting cost and system complexity.
