Advantages of Polyimide Heaters?
2023-04-11
Polyimide Heaters (FPC Heaters / FPC Electrothermal Films) are ideal for a variety of applications, especially when you need a low profile, fast response heater solution that provides precise heat distribution. Polyimide heating elements from branded manufacturers consist of a thin etched foil circuit laminated between two lightweight polyimide films for high dielectric strength, excellent chemical resistance and low outgassing characteristics.
In addition to being lightweight, Polyimide Heaters offer the following benefits:
1. Precise heat distribution and zoning with complex etched foil heating elements.
2. Typical 0.007" (0.18mm) ultra-thin profile to promote efficient heat transfer to the part
3. Very low outgassing for applications where contamination cannot be tolerated
4. High solvent and chemical resistance
5. Ideal for extreme temperature environments such as vacuum and space applications.
6. Translucent film facilitates visual inspection of parts and internal structure
Considerations When Choosing Polyimide Heaters Polyimide Heaters can be a good choice when the following apply:
1. Silicone rubber or other flexible layered materials cannot be used
2. Requires high power density (watt density)
3. Chemical Exposure
4. Outgassing may cause contamination, fogging or other undesirable problems
5. Exposure to radiation, such as in satellites
6. Requires precise contours such as holes, notches, cuts, etc.
7. Need to integrate sensors, thermal fuses, connectors, etc.
