PI Heating Film Customizable Yellow & Amber Kapton PI Heating Element With Etched Foil, Ideal For Automotive Seat Heaters
Engineered for demanding automotive environments, our etched foil Polyimide (PI) heating film delivers superior heating performance in an ultra-thin, flexible package. The precision-etched alloy foil is hermetically sealed between two rugged polyimide layers, available in both Yellow PI and Amber PI grades to match your specific material standards.
What sets this heater apart is its unique combination of thinness, bendability, and thermal stability – making it an ideal choice for car seat heaters, seat cushion heating sheets, and complete seat heating systems across passenger cars, EVs, and new energy vehicles. Whether for aftermarket upgrades or OEM integration, our film heaters offer dependable warmth, rapid response, and extended service life, all in a lightweight design that fits seamlessly into tight spaces.
-
Fast lamination compatibility – designed for quick and efficient lamination cycles, boosting production throughput.
-
Excellent dimensional stability – maintains precise alignment and flatness throughout the lamination process.
-
Superior electrical, chemical & thermal properties – ensures reliable insulation, corrosion resistance, and heat tolerance in demanding environments.
-
Optimized glue flow control – promotes uniform adhesive distribution, reducing voids and improving bond strength, which is especially critical for high-quality FPC lamination.
Our heating film offers two PI color choices (Yellow and Amber Kapton®-type), precision-etched foil for uniform heating, and an ultra-thin profile (0.13–0.22 mm) that feels completely unobtrusive. Its flexibility allows seamless adaptation to curved seat surfaces while withstanding millions of flex cycles. With strong dielectric insulation, moisture resistance, rapid heat-up, and a wide thermal range, this heater is built for year-round automotive use. Plus, we support full customization of size, circuitry, resistance, voltage, leads, and terminals.
