Polyimide Heaters
All Flex’s Polyimide Flex Heaters are a versatile solution for a variety of design challenges! Use a Polyimide Flex Heater for designs with a low profile, tight bend radius, or that require a high degree of thermal control.
When to Use Polyimide Heaters
- When you need a low profile that can’t fit within component clearances or between features without forcing changes in the overall package design
- When high thermal control is desired in the thinnest construction possible
- In applications where a tight bend radius is required
- When weight constraints are a factor
- When the heater will be exposed to solvents that may deteriorate it
- Polyimide heaters are excellent for low outgassing applications
All Flex can provide assembly options for heaters in-house! Explore our comprehensive heater assembly services to learn more.
Polyimide Heater Features
- Thinnest profile option, between .0045″ – .010″
- Standard polyimide heaters can peak at 300°F/150C, can go to higher temperatures for short periods
- Reliable conformance to curved & irregular surfaces, with the ability to wrap as tight as .25″ radius
- Improved thermal transfer compared to silicone rubber & offers a quicker response on thermal delivery to the surrounding mass
- Better chemical resistance from solvents
- No oil residue is emitted, making polyimide flex heaters cleaner than silicone rubber heaters
- Can be added later in the design process due to the thinness of the heater
