Polyimide film heater
Polyimide etched-foil heater
Thin etched-foil polyimide heater for tight clearances and flat or gently curved surfaces. The published thickness starts near 0.15 mm, inside a typical design window of 0.1–1.5 W/cm².

Where this applies
Tight-clearance surfaces that need a lightweight etched-foil heater bonded to a flat or gently curved part.
Thickness and watt density are the flexible-heater hub's published typical window, not a guaranteed rating for every outline. Final voltage and watt density are set from the thermal brief. No dielectric withstand voltage is published for this film.
Questions
How thick is the published polyimide build?
The hub lists thickness from about 0.15 mm for polyimide, upward from there.
Is the watt density a fixed rating?
No. 0.1–1.5 W/cm² is the published typical design window. The thermal brief sets the value for a given outline.
