FAQ

What is a polyimide heater?

A polyimide heater is a thin, flexible heating element made using polyimide film as an insulating layer. It provides efficient and uniform heating in compact and lightweight designs.

Can polyimide heaters be customized?

Yes, polyimide heaters are highly customizable. They can be designed to fit specific shapes, sizes, and wattage requirements. Custom configurations also include multiple heating zones, varied watt densities, and different voltage options to meet unique application demands.

How are polyimide heaters mounted?

Polyimide heaters often come with an adhesive backing for easy installation on flat or curved surfaces. For more demanding environments, custom mounting options, including mechanical fasteners or integration into larger assemblies, can be provided.

Are polyimide heaters resistant to chemicals and moisture?

Yes, polyimide heaters have excellent resistance to chemicals, moisture, and humidity. This makes them suitable for environments exposed to harsh chemicals or variable weather conditions, ensuring consistent performance without degradation.

What applications use polyimide heaters?

Polyimide heaters are versatile and used in a variety of industries, such as aerospace (to prevent condensation), medical devices (for heating diagnostic equipment), automotive systems (like battery warming), and consumer electronics (to ensure smooth operation in cold environments). They are also found in 3D printing, laboratory equipment, and satellites.
