Product structure:

Polyimide film heaters are composed of heating resistors (such as metal foil, alloy resistance wire, etc.) and high-performance polyimide insulation films. The heating resistor is sandwiched between two layers of polyimide film, and its high-temperature working stability is ensured by advanced bonding and packaging technology.

Main features:

• High temperature tolerance: The polyimide material itself is resistant to high temperatures and can usually be used for a long time in the range of -200°C to 200°C, and can withstand temperatures up to 300°C for a short time.
• Efficient heating and fast response: The excellent thermal conductivity of the heating resistor element enables the heater to heat up quickly, usually reaching the required temperature within a few seconds, which is suitable for scenarios with high temperature response requirements.
• Lightweight and thin: The thickness of polyimide film is extremely thin (usually around 0.1mm), light weight, good flexibility, will not increase the burden on the equipment, and is suitable for occasions with limited space.
• Chemical resistance and high insulation: Polyimide film has strong chemical corrosion resistance and insulation, suitable for use in harsh environments, and effectively protects internal components.

Advantages:

• High temperature uniformity: Polyimide film heaters can provide a uniform heating surface to ensure the consistency of temperature on the working surface, which is very suitable for precision heating needs.
• Strong flexibility and good adaptability: It can be installed on various curved, curved or irregular surfaces, and is widely used in electronic equipment, medical instruments, laboratory equipment and other equipment that require customized heating.
• Energy saving and high efficiency: The heater has efficient heating characteristics, and the low power consumption meets the energy-saving requirements, especially for equipment that runs stably for a long time.

Application fields:

• Aerospace: In high altitude and space environments, strict requirements are placed on temperature stability and heating. Polyimide film heaters are used as temperature control devices for internal components of satellites and spacecraft.
• Laboratory instruments: such as microscopes, constant temperature equipment, gas chromatographs, etc., polyimide film heaters help maintain the precise temperature environment of the instrument.
• Electronic equipment: used to heat sensitive components such as batteries, LCDs, cameras and sensors to ensure that the equipment can still work normally in low temperature environments.
• Medical equipment: suitable for medical instruments such as blood analysis equipment and body temperature maintenance equipment, providing precise temperature control to ensure the stability of experimental and surgical environments.
• Automotive industry: can be used for antifreeze and heat preservation of automotive batteries and sensors to ensure stable start-up and operation of cars in cold environments.

Typical application cases:

• Battery heating of drone equipment: In low temperature environments, polyimide film heaters can be used to heat batteries and extend the battery life of drones.
• Temperature control system of industrial equipment: in industrial environments that require high temperature heating, it can be installed on the surface of the equipment to maintain the constant temperature environment required for production.
• Sensor and display protection: used for heating sensors and LCD displays to ensure that the equipment works normally in low temperature or high humidity environments, suitable for outdoor electronic devices.

Summary:

Polyimide film heaters have excellent performance in high-precision, space-constrained, and temperature-controlled environments due to their high temperature resistance, light weight, and uniform heating. They are an indispensable heating solution in aerospace, medical, electronics, and industrial fields, and can meet the flexible, energy-saving, and efficient heating needs of modern equipment.
