PI heaters, also known as polyimide heaters, provide thin, lightweight, and flexible heating for precision applications where fast thermal response and uniform heat distribution are required. EaseWise PI heaters are manufactured by etching NiCr circuits onto polyimide film and laminating them with pressure-sensitive adhesive. They are widely used in EV battery thermal management, semiconductor processing, medical equipment, aerospace instrumentation, and other applications where heating elements must fit tight installation spaces.
Key Features of Polyimide Film Heater Applications
- Ultra-Thin Profile — As thin as 0.18mm, the polyimide film heater fits into close-tolerance assemblies where installation space is limited.
- Fast Thermal Response — Low thermal mass enables rapid heat-up and cool-down cycles for precise temperature control.
- Uniform Heat Distribution — Precisely etched circuits provide consistent heating across the designed heating area.
- Wide Temperature Range — Suitable for applications requiring reliable operation from -60°C to 200°C.
- Built-in Sensor Options — NTC, PT100, PT1000, and K/J thermocouples can be integrated for closed-loop temperature control.
- Custom Shape & Size — Custom outlines up to 500mm × 500mm can include cutouts, mounting holes, and other design features.
- Adhesive Backing — Optional 3M PSA or silicone pressure-sensitive adhesive enables direct bonding to compatible surfaces.
Applications of Polyimide Film Heater Applications
EV Battery & New Energy
PI Heater for EV Battery Heating
In EV battery packs and energy storage systems, polyimide film heaters provide localized heating during cold-start and low-temperature conditions. Their flexible, low-profile design allows PI heaters to be integrated onto battery module surfaces or into other space-constrained areas where conventional heating elements may be difficult to install.
Custom heater dimensions, power output, and temperature-sensing options can be matched to the battery structure and temperature-control requirements. For application-specific configurations, see our PI heater solutions.
Semiconductor & Electronics
PI Heater for Semiconductor Manufacturing
Polyimide film heaters are used in wafer processing equipment, chip testing fixtures, and IC packaging systems where localized temperature control is required. Their thin, flexible construction allows PI heaters to be integrated into compact fixtures, vacuum equipment, and other space-constrained assemblies.
Integrated RTD or thermocouple options can support closed-loop temperature monitoring for semiconductor manufacturing equipment and precision instrumentation. For custom dimensions, power, and sensor configurations, see our custom PI heater configurations.
Medical Devices & Diagnostics
PI Heater for Medical Equipment
Polyimide film heaters are used in blood analyzers, PCR systems, and fluid warming equipment where compact and controlled heating is required. Their thin, smooth polyimide construction supports cleanable heating components and compact integration in precision medical and diagnostic equipment.
Custom shapes with integrated temperature sensors can be designed for disposable cartridges, diagnostic modules, and other medical equipment. Heater dimensions, power output, and sensor placement can be adapted to specific equipment and installation requirements.

Frequently Asked Questions
PI heaters are widely used in EV battery packs, 3D printer hot ends, semiconductor wafer processing, medical diagnostic instruments, aerospace avionics, and any application requiring ultra-thin, precise heating in confined spaces.
PI heaters are significantly thinner (as low as 0.18mm vs 1.5mm+), have higher power density, and offer faster thermal response. Silicone heaters are better for larger surfaces and lower cost; PI heaters win when space is tight and precision matters.
Yes. We etch circuits to your exact outline — including cutouts, mounting holes, and irregular shapes — up to 500mm × 500mm. Provide a DXF or PDF drawing and we’ll match it.
Yes. 3M PSA and silicone pressure adhesive options are available. The adhesive allows direct bonding to battery modules, instrument housings, or metal surfaces without additional mounting hardware.
