Kapton Polyimide Flexible Heater

A polyimide flexible heater is an innovative solution for applications requiring uniform heat in tight spaces. Made from Kapton polyimide film, it offers exceptional thermal stability, chemical resistance, and electrical insulation. Its thin profile allows installation in places where traditional heaters cannot fit, while its low mass delivers fast heat transfer and minimal thermal lag.

With our custom polyimide flexible heater service, you can specify exact dimensions, watt density, voltage, lead configuration, and even integrated sensors. This makes it an excellent choice for precision instruments, battery warming, aerospace electronics, medical diagnostic equipment, and satellite systems.

Our engineering team designs each custom flexible heater to maximize efficiency and longevity. We utilize computer-controlled etching for consistent element spacing, ensuring uniform heat distribution without hot spots. For projects requiring rapid prototyping or small-batch production, we can deliver samples quickly while maintaining strict quality control.

Applications

The polyimide flexible heater is widely used in industries where space is limited but precise heat is required:

Medical Devices – Blood analyzers, diagnostic instruments, infusion apparatus

Aerospace Systems – Satellite electronics, sensors, and battery warming

Electronics – LCD displays, sensors, and test equipment

Industrial Equipment – 3D printers, analytical devices, and battery packs

Case Study – Infusion Apparatus

One of our notable projects involved integrating a custom polyimide flexible heater into a high-precision infusion apparatus used in advanced medical facilities.

Project Challenge:

The client needed to keep infusion liquids at a stable 37°C ±0.5°C during delivery, even in rooms with fluctuating ambient temperatures between 18°C and 28°C. Traditional heaters caused uneven temperature zones, sometimes exceeding 1.5°C variation, which affected patient comfort and dosage accuracy.

Our Solution:

Our engineering team designed a Kapton polyimide flexible heater with a tailored contour to fit the device’s fluid channel. The heater’s profile was only 0.2 mm thick, ensuring minimal weight and no interference with the device’s internal layout. Using etched foil elements with optimized spacing, we achieved temperature uniformity within ±0.3°C across the heated surface.

Key Results:

Warm-up Time: Reduced from 3 minutes (previous model) to 1 minute 40 seconds

Temperature Stability: Maintained 37°C ±0.3°C during continuous operation

Energy Efficiency: Power consumption lowered by 18% compared to the old heating module

Device Lifespan: Projected increase of over 20% due to reduced thermal stress
