Product Name:Electrothermal polyimide film etched heating pad 

Product Description

Polyimide film type heater is a kind of sandwich structure of the translucent metal flexible electric heating piece. Also known as metal electric film, its upper and lower sides of good heat resistance, good insulation properties of the polyimide film, intermediate resistive circuit is made of special alloy foil. It because of the characteristics of temperature and resistance to chemical corrosion and widely used.I n the limited space and weight, electrothermal film exposed to vacuum, oil or chemicals such as environment, is the ideal choice for metallic electrothermal film.  electrothermal film exposed to vacuum, oil or chemicals such as environment, is the ideal choice for metallic electrothermal film. Metal electrothermal film has excellent dielectric strength, excellent resistance to electric intensity and excellent heat transfer efficiency, heating element using special gold, has excellent resistance stability and electro-thermal conversion rate.. Which makes it can be widely used in heating area and be able to get fairly high temperature control precision.

  Polyimide film electric heater advantage
  1.Planar heating, high thermal efficiency, energy saving
   Polyimide film electric heater is planar heating material, with the heated body formed to maximize the thermal conductivity, small heat transfer resistance.Ohmic heating heat can be quickly transferred to the heated body, and because of this heating good thermal conductivity, so the heating temperature is not too high,not red, glowing, radiant heat loss is very small,hence the electric membrane made of electric appliances, thermal efficiency is very high, generally around 90%. As the traditional point of heat dissipation area is small, and other objects to be heated depends on indirect conduction, the electrothermal conversion process, the heat generated by power transmitted can be heated quickly, resulting in the heat of the heating element is too concentrated, the element itself becomes hot quickly, a large part of energy into a light energy loss, resulting in electric conversion efficiency is low.
   Polyimide film type electric heater can be heated for the location of the heating. You only need to put them in need to heating the surface of the parts. The light-weight structures in the electric leaf provide close thermal coupling between components and radiator. In the area of heat loss is bigger, you can even specify the configuration using higher power density heating mode.
   2.Preheat fast, long life, easy to damage
   For larger surface area of the polyimide film-type electric heater of the heat transfer element plates foil effect higher than the winding type heater. Therefore polyimide electrothermal film is formed between the resistive element and heat sink thermal difference is not very obvious, electric film remains relatively low temperature state. General electric heat source is always used under hot condition, so it is prone to oxidation, joint caused by open circuit. The electric film work due to a large contact surface, fast heat conduction, so its temperature is low, which improves the ohmic heating electric film material in the oxidation state of their own problems, prolongthe service life.
   3.Overall optional strong, wide application
   Electric membrane can be made in film, linear, can according to the need of the interception of different length and size, with wrap, paste and winding is fixed in the heated surface, the complex shape of the vessel or the work surface can be coated. The characteristics of electric heating film application range of the electrothermal film heating element is much wider than the traditional.
   4.No open flame, safety and reliability
Electric film in electric conversion process does not produce fire. When the electric film heater is heated to 100 °C boiling state, the electric film does not burn paper, cotton, matches, it will not ignite in contact with. Therefore, it is suitable for some electric film heating insulation needs, but does not allow application of special places exposed to open flames.
   5. Save space,reduce weight
   Polyimide metal electric heating film weight usually only (0.04 q/cm2), measuring the thickness of element only (0.12mm). For areas with limited space, such as defense electronics, aerospace equipment, portable medical equipment, high-density electronic devices, polyimide film electric heater can meet your requirement.
   6.Anti-corrosion, anti-radiation
   Resistant to most chemicals, such as acid and solvent corrosion. Resistant to 106 rads of radiation.
   7.Custom Device
   Custom options can provide the perfect complete solution, significantly reducing assembly time and improve productivity. Custom configuration provides a balanced heating output performance, in order to improve the processing capacity and productivity.
