I. Overview

Kapton flexible electric heating plates can be provided in various shapes, specifications and power sizes. The electric heating plate has a very thin structure (the maximum thickness is only 0.25mm), and can be arbitrarily bent according to the shape of the workpiece to ensure close contact with the workpiece and ensure maximum heat energy transfer. Kapton flexible electric heating plate is a semi-transparent or fully transparent metal flexible electric heating film, the upper and lower surfaces are a kind of film with good rigidity and temperature, excellent insulation performance, such as Kapton film, Teflon film and silicone film, the middle is Resistive circuits made of special alloy foils. It provides a more uniform thermal field, shorter heating time and faster response time than the filamentary electric heating structure, lower power load and longer service life than the filamentary electric heating structure. According to user requirements, this product can provide pressure-sensitive version of PSA or epoxy adhesive for installation.

Due to its light weight, high structural strength and even heat generation, this product has been widely used in the antifreeze and heating of satellites, aerospace equipment and mobile instruments.

According to the requirements of heating the workpiece, this product can be made into various heating circuits. For example, some circuits can be required to be heated, and some circuits can be used as heat tracing, so the design is very flexible.

The flexible electric heating plate is resistant to oil, chemical corrosion and radiation, and can be widely used in harsh working conditions.

2. Features

1. Occupy very small space; very light weight; very thin thickness.

2. Extremely soft, its minimum bending radius is only about 0.8mm.

3. The shape and size are extremely flexible, especially suitable for making flexible electric heating film elements with small surface area.

4. The surface heating method is adopted, and the allowable surface power load is extremely large, and the maximum can reach 7.8W/cm2. Therefore, this product has the characteristics of good uniform heating performance and fast heating rate.

5. Different heating power requirements and heating temperature requirements can be met in different areas. It can be designed as required to achieve temperature distribution on the heating surface.

6. The thermal inertia is small, the temperature control precision is high, and the heating speed is fast.

7. The insulating film as a protective layer has extremely low saturated vapor pressure, extremely low outgassing, and at the same time has excellent chemical corrosion resistance, antibacterial properties and radiation resistance. Therefore, this series of coiled electric heating plates is suitable for vacuum environments, environments that are in contact with petroleum and most chemicals (such as acids, chemical solvents, and a ship's lye).

8. It can be easily integrated with temperature controller or sensor.

9. Products with PSA self-adhesive are more convenient and quick to install (applicable to 1W/cm2 and 2W/cm2). This electric heating plate can also be installed by the user by mechanical crimping or epoxy adhesive bonding.

10. This series of products is safe, reliable and has a long service life.

3. Typical application fields

1. Scientific analysis instruments, such as: providing a constant temperature source for thermal conductivity testers, medical instruments and stabilizing the working temperature of optoelectronic components, etc.

2. In a cryogenic environment, make the instruments and equipment reach a safe working temperature, such as: artificial satellites, instruments in space vehicles, and instruments and instruments used in high latitude areas, such as card readers, liquid crystal displays LCD and other instruments .

3. Vacuum heating and baking fields.

4. Military industry, such as missiles, ships, tanks, radars.

5. Defrost sheets for car rearview mirrors, snow removal and defrost heating elements for antennas or radars, and speed control resistors.

6. Medical insurance and beauty equipment industry.
