Thin-film bonding and temperature feedback
Kapton Polyimide Film Heater 400v: A polyimide heater has low thermal mass and should be supported by a compatible substrate. Supply an outline drawing that identifies cutouts, lead exit and the area available for bonding.
Review adhesive temperature limits and uniform contact pressure. Place the sensor where the controlled surface temperature matters, and keep the circuit away from sharp folds or screw holes.
For Kapton Polyimide Film Heater 400v, use the listed 400v as catalog identifiers and confirm the complete electrical and dimensional combination before calculating current, selecting a supply or fixing the mounting pattern.
The archived configuration for Kapton Polyimide Film Heater 400v lists Power density range: 0.03w/cm2~2.5w/cm2 / (0.19w/inch2~16.13w/inch2); Voltage: 3.7v-220v; Material: polyimide; Power: 1-6.5w/cm2. Treat these as reference options and reconcile them with the named configuration and installation drawing before quotation.
For Kapton Polyimide Film Heater 400v, send the supply, continuous and peak temperature, mounting drawing, lead exit and quantity. Include the heated medium and control method so the quoted configuration can be checked against the actual duty.

1. Basic Product Definition
An ultra-thin flexible resistance heating element laminated under high temperature, with polyimide (PI/Kapton) film as insulating substrate and etched metal foil heating circuit inside.
Basic Structure
Double-layer PI film + etched metal heating foil + optional back adhesive (3M pressure-sensitive adhesive, thermal conductive adhesive)
1：Ultra-thin & Flexible With a thickness of only 0.15~0.3mm, it can be bent to fit curved and special-shaped workpieces and fit narrow installation spaces; extremely lightweight, ideal for weight reduction in aerospace and lithium battery industries.
2：Fast Heating & Uniform Heat Distribution The etched metal circuit features low thermal capacity for rapid temperature rise and minor surface temperature difference, supporting high-precision temperature control for precise constant-temperature scenarios.
3：High Temperature Resistance & Excellent Insulation Continuous operating temperature: -60~150℃, short-term peak temperature up to 200~250℃; dielectric strength ≥1000V, insulation resistance ＞100MΩ, UL94 V-0 flame retardant grade.
4：Chemical Resistance & Low Outgassing in Vacuum Resistant to oil, acid, alkali and organic solvents; low volatile outgassing under vacuum conditions, specially applied to semiconductor and aerospace vacuum equipment.
5：Radiation, Moisture & Mildew Resistant Suitable for harsh environments such as outdoor, aerospace and precision laboratories with long service life.
6：Fully Customizable Customizable in any shape (strip, ring, special shape), voltage (12V/24V/110V/220V), power, wire outlet position, and integrated PT100 temperature sensor.
The thickness is about 0.3mm, the lead wire is 150mm. backing adhesive by default.
The pi film is a high-temperature electric heating film, and the surface temperature of theproduced product is
less than 200 oC;PET is a low-temperature electric heating film, and the surface temperature of the productproduced is ≤ 100 0C
Welding front protruding through insulation with red adhesive dotsThe front of the riveted joint protrudes
outward and is insulated with insulating tape
With temperature measuring wires: thermistors, K-type thermocouples, PT100

Polyimide heaters are known for their flexibility, durability, and resistance to high temperatures and harsh
environments. They are typically used in applications where a thin and flexible heating element is required
such as in medical equipment, aerospace applications, and electronics.
One of the advantages of polyimide heaters is their ability to conform to irregular surfaces, which makes
them ideal for use in equipment that has complex geometries or tight spaces. They can also be easily
customized to fit specific shapes and sizes, which allows for a high degree of design flexibility.
Polyimide heaters are available in a range of power ratings, from a few watts to several kilowatts, and can
be designed to operate at different voltages and frequencies. They can also be equipped with
temperature sensors and other control devices to ensure precise temperature control and protection
against overheating.
Overall, polyimide heaters are a reliable and cost-effective solution for a wide range of heating applications
offering excellent thermal stability, resistance to moisture and chemicals, and long service life.
