This electric heater has a thin structure (up to 0.25mm thickness) and can be bent arbitrarily according to the shape of the workpiece to ensure close contact with the workpiece and ensure maximum heat transfer. PI flexible heater is a translucent or fully transparent metal flexible electric heating film, its upper and lower surface is a kind of good temperature resistance, excellent insulation performance of the film, the middle is made of special alloy foil resistive circuit.
Compared with the filament electric heating structure, it can provide more uniform thermal field, shorter heating time and faster response time, lower power load and longer service life.
According to customer's request, this product can provide pressure sensitive version of PSA or epoxy adhesive for installation.
Due to its light weight, high structural strength and uniform heating, the product has been widely used in the heating of medical, electronic, aerospace and mobile instruments.
This product working voltage :1V-100v, according to the requirements of heating workpiece, can be made into a variety of different heating circuit, for example, you can require some of the circuit heating, some circuit as heat preservation tracing, so the design is very flexible.
PI film heater is resistant to oil, chemical corrosion and radiation, and can be widely used in harsh working conditions.
Product Characteristics
◾ 1. occupy a small space; Light in weight; The thickness is thin.
◾ 2. good softness, its minimum bending radius is about 0.8mm.
◾ 3. the shape and size of flexible customization, especially suitable for the production of small area of flexible electrothermal film components.
◾ 4. the use of surface heating, allow large surface power load, the maximum can reach 7.8/cm2. Therefore, this product has the characteristics of good uniform heating performance and fast heating rate.
◾ 5. in different areas can meet different heating power requirements and heating temperature requirements, can be designed according to the requirements, to achieve the temperature distribution on the heating surface.
◾ 6. the thermal inertia is small, the temperature control precision is high, the heating speed is fast.
◾ 7. As a protective layer, the insulating film has a very low saturated steam pressure, low gas release, and excellent chemical corrosion resistance, antibacterial performance and radiation resistance. Therefore, the flexible heater series products are suitable for vacuum environment, with petroleum and most chemicals (such as acid, chemical solvents, general lye) contact environment.
◾ 8. It can be easily integrated with temperature controller or sensor.
◾ 9. Products with PSA adhesive are more convenient and fast to install (applicable to 1w/cm2 and 2w/cm2), and can also be installed by the user with mechanical crimp or epoxy adhesive.
◾ 10. this series of products are safe, reliable, long service life.
PI film heater products are mainly suitable for:
◾ 1. scientific analysis instruments, such as: for thermal conductivity measurement instrument to provide constant temperature source, medical instruments and stable optoelectronic components working temperature.
◾ 2. in the cold environment, make the instrument and equipment to reach the safe working temperature. For example: artificial satellites, instruments in space vehicles and instruments and instruments used in high latitude areas to prevent low temperature, such as card readers, liquid crystal display LCD and other instruments.
◾ 3. Vacuum heating and baking.
◾ 4. military industry, such as missiles, ships, tanks, radar.
◾ 5. car rearview mirror defrosting piece, antenna or radar hail, defrosting heating element and speed regulation resistance piece.
◾ 6. Health care and beauty instrument industry.
