High Efficiency And Energy Saving Polyimide Film Heater

Polyimide is a lightweight and thin organic polymer film known for its excellent tensile strength, tear resistance, and dimensional stability. This type of heater is ideal for applications requiring low outgassing in vacuum environments, or resistance to radiation, fungi, and chemicals. Polyimide is also solvent-resistant. Due to their unique properties, polyimide heaters find applications across various industries and sectors. Below are some common uses of polyimide heaters: Aerospace: Polyimide heaters are used in aerospace for de-icing, anti-icing, and temperature maintenance of critical components such as wings, leading edges, and engine nacelles. Their lightweight and flexibility make them suitable for aerospace applications where weight and space constraints are significant. Medical and Laboratory Equipment: Polyimide heaters are employed in medical devices and laboratory equipment for applications like sample preparation, reagent heating, analytical instruments, DNA sequencing, and temperature control in incubators and diagnostic devices. Semiconductor and Electronics: In the semiconductor and electronics industries, polyimide heaters are used for wafer processing, chemical vapor deposition (CVD), and rapid thermal processing (RTP). They provide precise and uniform heating to ensure optimal manufacturing conditions. Automotive: Polyimide heaters are utilized in the automotive industry for heated seats, side mirrors, windshield defogging, fuel line heating, and battery heating in electric vehicles. Their flexibility and ability to conform to complex shapes make them ideal for automotive heating solutions. Food and Beverage Industry: Polyimide heaters are integrated into food and beverage processing equipment to maintain consistent temperatures during food processing, packaging, and sterilization. 3D Printing: Polyimide heaters are used in 3D printers to deliver uniform and controlled heating to print beds, ensuring optimal printing conditions and preventing warping or uneven cooling of printed objects. Oil and Gas: These heaters are widely applied in the oil and gas sector for pipeline heating elements, flow assurance systems, and instrumentation. They help maintain required temperatures and prevent hydrate or wax formation in pipelines. Environmental Testing: Polyimide heaters are used in environmental chambers and testing equipment to simulate specific temperature conditions for product testing, reliability trials, and accelerated aging studies. Aerospace and Defense: In aerospace and defense, polyimide heaters are used in satellite components, avionics, radar systems, and military equipment, providing reliable and precise heating in extreme environments. Consumer Electronics: Polyimide heaters are integrated into consumer electronics such as smartphones, tablets, and wearables for battery heating, display defrosting, and maintaining optimal operating temperatures for electronic components. These examples highlight the broad range of applications for polyimide heaters. Their versatility, high-temperature resistance, and flexibility make them indispensable in industries requiring efficient and customizable heating solutions.

Notes:

The minimum width of polyimide/Kapton heaters is 8mm for one-side lead wire exit and 5mm for two-side lead wire exit.

The maximum width of polyimide/Kapton heaters is only limited by the number of polyimide film rolls. Therefore, there is no restriction in one dimension. Wider heaters can be produced for large-volume demands.

The maximum operating temperature depends on various factors. 260°C applies to aluminized polyimide heaters without adhesive backing.
