PI Heater Applications
PI heater is a polyimide film heater used for industrial heating applications. The PI heater provides flexible, ultra-thin and precise temperature control. Because the PI heater can be customized for voltage, watt density, size and connector, it is widely used in battery heating, medical devices, semiconductor processing and display equipment.
Polyimide Heater for Small Space Precision Heating
Polyimide heater (PI heater) is a lightweight, ultra-thin and flexible heating solution engineered for precise temperature control in limited installation space. It is manufactured by etching the heating circuit on a polyimide film, then laminating with pressure-sensitive adhesive. Polyimide heater is widely used in industrial automation, semiconductor devices, battery heating, instrumentation, medical devices and new energy applications.
Why Polyimide Heater is Selected in Industrial Applications?
Compared with silicone heater or mica heater, polyimide heater offers thinner thickness and higher power density. It can be used in close tolerance assemblies where space is limited, but accurate and fast heat rise is demanded.
- Ultra-thin design (as thin as 0.18mm)
- Fast heating response and even heat distribution
- Built-in thermistor or RTD optional
- Wide operating temperature range
- Excellent chemical resistance and moisture resistance
- Power range: 1W – 400W
Industries Using Polyimide Heater
- Semiconductor and wafer processing
- Sensor heating and instrument warm-up
- Medical diagnostic devices
- New energy lithium battery heating
- 3D printer nozzle and hot end system
- Automation / robotics flexible heating
