Polyimide Heaters

When to Use

• When you need a low profile that can’t fit within component clearances or between features, not 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 heater will be exposed to solvents that may deteriorate it
• Polyimide is excellent for low outgassing applications
• All Flex can provide assembly options for heaters in-house

Features

• Thinnest profile option, between .0045″ – .010″
• Standard polyimide heaters can peak at 300°F/150C, can go higher for short periods
• Reliable conformance to curved and irregular surfaces, with the ability to wrap as tight as .25″ radius
• Improved thermal transfer compared to silicone rubber and offers a quicker response on thermal delivery to the surrounding mass
• Better chemical resistance from solvents
• No oil residue is emitted, making them cleaner than silicone rubber heaters
• Can be added later in the design process due to the thinness of the heater
