Introduction to the advantage and performance of polyimide heater


Polyimide flexible heaters generate just the right amount of heat for the application. These types of heaters, when used, can be attached to appliances of different sizes and capabilities. Polyimide flexible heaters are composed of etched foil element layers, and the flexible heaters are very thin, with a thickness of 0.13-0.4mm. The heater has a watt density of 2.5 to 50W/in 2 . Advantages of polyimide heaters include:

Can withstand the temperature of -40℃-250℃

resistive properties as it will not crack or tear

Minimal outgassing in vacuum

Uniform heat distribution and good stability

good heat transfer capability

Adjustable thermostat, temperature fuse, temperature control switch

Customizable voltage 1.5V-380V

The use of polyimide flexible heater

Due to the thin and bendable nature of polyimide flexible heaters, polyimide flexible heaters can be used in applications where additional weight is an issue for product components. It can also be placed on devices with minimal space available. Therefore, flexible heaters can be accommodated without any tuning in the application. The flexibility of polyimide allows the heater to be applied to curved and irregular surfaces without fear of the heater falling off during application.


The polyimide heater will not produce other gases in the application, and most manufacturers will pay attention to this aspect when choosing a suitable heater, so this polyimide flexible heater can be obtained by most manufacturers of favor. These entrapped gases can interfere with the sensor's use in closed environments. Therefore, the gas generated by the polyimide heating sheet will be reduced during production.


Polyimide heaters have good heat transfer properties and are often used in harsh environments where durability is required. They are widely used in de-icing mirror surfaces, heating batteries, military and medical industries. This heater can also be used in indoor and outdoor environments.


Polyimide flexible heaters are often used in small applications where heated temperatures are required. These flexible heaters typically provide temperatures of 250°C. Manufacturers often affect the service life of products due to temperature control during use. The glass of a car in a cold environment usually fogs up in the heat and cold, which blocks the driver's view, making it unsafe. The heater heats the glass of the car while heating to maintain the clarity of the glass.


The flexibility and lightweight nature of polyimide flexible heaters make them suitable for applications where increased weight and irregular curved surfaces are major concerns. Etched foil polyester heaters have a maximum element width of 590mm, making them a good choice for small applications. Additionally, the heater can be customized to be transparent when the application requires an aesthetic appearance.


Danyu is polyimide heaters are used in a wide range of applications in production, choosing the right type of flexible heater will produce stable heat without causing application damage or failure. It can also be customized according to the manufacturer's products.
