Polyimide heating film has become a preferred choice for industries that require thin, flexible, and durable heating solutions. Whether used in electronics, aerospace, medical devices, or automotive systems, these films deliver precise thermal control in a lightweight form. Among them, the 12v 12w PI polyimide heating film is widely adopted for compact applications where steady heat and high reliability are essential.
At Danyu Electronic, we specialize in producing polyimide heater films and Kapton polyimide heaters with strict quality standards, competitive pricing, and custom engineering support. Our advanced manufacturing process ensures every product meets international performance benchmarks.
If you’ve ever had to keep electronics stable in cold or fluctuating environments, you’ve likely come across the 12V 12W polyimide heating film. It’s a thin, flexible heating element built from polyimide film (also known as Kapton). The heater handles 12-vlotage and support 12watt, provides consistent, uniform heat while remaining extremely lightweight.
This type of heater is widely used in:
Yes. Kapton is a brand name created by DuPont, while polyimide is the generic term for the material. Both refer to the same class of high-performance polymer films.
So when you hear Kapton polyimide heaters, it simply means the heater is manufactured with DuPont Kapton or equivalent high-grade polyimide.
For buyers, the important detail is that polyimide maintains thermal and electrical stability even under harsh conditions, making it ideal for industrial and aerospace-grade applications.
A polyimide heater film is designed with multiple layers to provide durability, safety, and consistent heating:
This design allows for a thin, yet highly efficient heating element capable of precise temperature control even in compact or irregularly shaped devices.
Polyimide heater films are available in different designs depending on the application:
This variety allows engineers to choose heaters based on shape, installation method, and thermal performance requirements.
Key reasons why industries choose polyimide heaters:
Compared to silicone heaters, polyimide films excel in compact, high-precision environments where thickness and weight matter.
Polyimide heater films can typically withstand continuous operation at 200–260°C, with some high-grade films tolerating short-term exposure to even higher temperatures. This makes them suitable for applications in medical devices, laboratory equipment, aerospace, and electronics where stable heating is critical.
The high-temperature tolerance also allows these heaters to operate safely in confined spaces, providing reliable heat without risking fire hazards or material degradation.
The standard specifications for a 12v 12w polyimide heating film are:
| Parameter | Specification |
| Rated Voltage | 12V DC |
| Rated Power | 12W |
| Heating Element | Etched copper or nickel alloy |
| Insulation Material | Polyimide film |
| Temperature Range | -200°C to +260°C |
| Thickness | 0.13–0.40mm (customizable) |
| Surface Adhesive | Optional pressure-sensitive tape |
| Tolerance | ±5% power, ±5°C temperature |
| Operating Life | 10,000+ hours (dependent on application) |
| Certifications | ISO9001 compliant |
| Applications | Electronics, battery warming, medical devices, sensors, optical instruments |
Polyimide film is highly versatile and not limited to heaters. Its applications include:
Its combination of flexibility, thermal resistance, and chemical stability makes it indispensable in modern electronics and industrial applications.
| Feature | Polyimide Heater Film | Silicone Heater |
| Thickness | Ultra-thin (0.1–0.3mm) | Thicker (0.5–1.5mm) |
| Flexibility | High, even around tight curves | Moderate |
| Max Temperature | 260°C | 200–230°C |
| Weight | Extremely light | Heavier |
| Chemical Resistance | Excellent | Good |
| Durability | High in clean environments | More rugged, outdoor capable |
| Cost | Higher | Moderate |
So in conclusion:
No. Polyimide is naturally flame-resistant and maintains structural integrity under extreme heat.
Even in extreme conditions, polyimide maintains structural integrity, ensuring safe and reliable operation. Its resistance to fire and chemicals provides additional peace of mind for engineers and designers.

1. Can I use polyimide heaters for battery warming in cold environments?
Yes. Polyimide heaters maintain stable temperature control in low-temperature conditions and are widely used in battery management systems.
2. Are Kapton heaters reusable if removed from a surface?
Generally, the adhesive layer is designed for one-time application. However, the film itself can be reused if installed carefully with additional adhesive.
3. How do I choose the right wattage for my application?
Consider the size of the heating area, desired temperature, and power source. Our engineers can provide calculations to match wattage with your requirements.
4. Is polyimide heating film compatible with curved surfaces?
Yes. The thin and flexible nature of polyimide film allows it to conform to slight curves or irregular shapes without compromising performance.
5. What industries most commonly use Kapton polyimide heaters?
They are widely used in electronics, medical devices, automotive systems, aerospace, and industrial equipment requiring precise and reliable heating.
